I was contemplating between ceramic komado and charcoal summit.  I had inspected the summit at an Ace hardware and went to inspect the Komado Joe at the Costco show.  I was considering the jumbo joe and was about to pull the trigger on the purchase.  $1200 for the jumbo with the stand is a great price and all reviews put it right there with the green egg but at a better price.  The following reasons are what swayed me to the charcoal summit.  Weight; ceramic komado, especially the jumbo, was extremely heavy.  The weber rolls around nice and easy.  Not sure if i could lift it into the bed of my truck by myself to travel with, but it would certainly be easier than with the ceramic.  Fragility; I really did not read a terrible number of experiences with cracked kamados but did read some.  Gas assisted start; I just hate having to use the chimney all of the time, and with the weber I always still have that option if need be and I ran out of gas.  Ease of cleaning with the removable ash pan.  I have always loved this feature on the OTG and it just works great.  Kamado Joe however has a good looking ash removal system but just don't have experience with it.  I don't think the green egg has anything to help with ash removal, but I could be wrong.  And finally what finally pushed me over the edge, was that just two weeks ago, the latch broke on the door to my wsm 22" from something completely my fault.  I contacted weber and told them what happened.  On the two year old smoker they sent me a complete replacement door with no questions asked, no pictures, no managers approval required, no hassle.  3 days later, whole new door arrived at my house.  And this site if full of those stories and this is not my first experience with weber support.  I have never dealt with a company as good as weber when it comes to support.  So that's how I ended up with the weber charcoal summit but I am sure a ceramic will grill and smoke just as good if not better, but this is what i based my decision on.
Now onto the review.  For background I currently own OTG Kettle, Genesis 1000, WSM 22" and on the go grill.  I've spend one weekend and prepared two meals.  One was grilled chicken, squash, and abt and the other was pizza.  Performed just as well as the kettles when it came to the grilling.  Performed better with the pizza, because you can get the temperature up faster and maybe higher.  I don't know how hot it was because it pegged out the dial thermometer, but it was plenty hot enough.  I will look forward to performing my first smoke of a brisket this upcoming weekend.  I love it.  I think one of the problems that everyone has with the price is that they are just picturing some new version of the kettle.  You have to see it in person to realize just how massive it is.  I can tell you that I don't feel ripped off.  I love the lid, the hinge works great, and I have always loved the ash cleaner and this is the same old system.  Now onto my critiques.  You will need a long coal rake.  I have the cheap short one from amazon and I burned the hell out of my arms.  I may invest in the weber one once it becomes more readily available.  The gourmet grate is a pain.  I hate having to remove the center section separately.  I think I will try to find a way to fasten it to the grate with some stainless steel wire perhaps.  I found myself burning again trying to set the grate over the hot coals and getting the insert seated properly in the middle.  Was way more difficult that I thought it would be.  Maybe this is just me, as I have no previous experience with the gourmet grating system.  I think I need to find a good place to hang the grate when it is removed.  I didn't spring for the prep table version and without there is no place I have found good for hanging it.  On the kettle, I always hung it on the side.  But with the thick rim of the summit, this does not seem possible, and if you did, the center insert would fall out.  So I will need to work on this.  I purchased the weber grill cover even though it will be kept mainly under awning, but it is a small one, so I wanted to protect this grill as best as possible.  I cover all of my other grills.  I honestly have no idea how this thing can cost $60.  I imagine if it's like the others I will only get about 3 years out of it and then will need to purchase another.  This is the only thing that I may regret about my purchase.
Also, I would like to add that if anyone has not noticed, there are three leg supports on the bottom of the kettle, just like you see on the performer.  This even includes the standard summit charcoal like mine.  To me, that means it is likely that they may release a non summit version sometime in the future without the large base and assisted start.  Not sure how stable it would be without the large base and that big lid, maybe no hinge and just a removable lid with stainless gasket on it.  I guess we shall see.
Let me know if you have any specific questions and I'll try to address.
