If you look at any Go Anywhere gas grills, make sure you get one that has the "old" deflector/flavorizer bar and regular grill grate. The new ones are not very good, in my opinion.
If you find a new one that is a really good price, you can get this on Amazon.

I also just recently got this carry bag for my Go Anywhere.

It's heavy duty and has pockets for accessories and even 1lb propane bottles.
The Q1200 is a fantastic grill but heavier and a bit less portable. But, it's actually a workhorse and gets really, really hot for some serious grilling. I sold my 4 burner Genesis and use my Q1200 as my gasser at home. But, I could easily take it on the road, if necessary. But, I have the Go Anywhere for the camper along with my Jumbo Joe.
