I have had the same reaction to the new Genesis II grills that I have seen. I hope I am not allowing the shiny newness to cloud my judgment, but looking at them in person they DO seem to be of decent quality. As others have mentioned, I am glad they brought back the simpler open cart option. It does at least appear that they have tried to improve the burners and even the frame looks better to me. The real test will be to see how they hold up over a reasonable time frame. It would be nice if they offered an alternative to the painted steel frame. Unless cared for meticulously, it is doomed to rust out, at least in our salt air, wet Florida environment. If not on the Genesis, then at least the Summit grills should have this option.
I don't like it at all that Weber has pretty much gone the "make it in China" route. I felt that establishing the Spirit line as a lower cost Chinese alternative was PERHAPS an acceptable compromise, but Genesis and Summit grills could - and should - be made here profitably. It would justify an even higher price, in my view, IF they were truly US made. Nonetheless, while there is a lot of cheap junk from China there are also some good products. So, since I can't afford a new Weber, I will watch on the sidelines and troll Craigslist for when they start popping up there. The ability of the Genesis IIs to hold up and hold value will tell a lot. I know that the Genesis 300 series are getting easier to find at low prices due to the often-noted problems with rusty cart enclosures and failing legs.
Because of the deals on rust-ruined Genesis 300 series grills, I am getting more interested in restoring these and addressing at least part of the problem with stainless steel replacement bottoms and backs that my sheet metal shop owner friend has made for me. Hopefully, some of the rust-repair ideas such as Eastwood POR 15 that I learned about on this forum will also help turn around salvageable examples and give them many more years of service. As grills go, I think the 300 series are actually excellent cookers that also look nice on the patio.
So, I think the Genesis II grills do show promise, but I will admit that there are questions left that only time will answer.
