I admit I am a bit of a pellet fanboi these days, but you may want to consider some of the pellet grills that can do high heat and low n slow as an alternative. The budget may be a bit difficult to fit into, but I think some might come close.
I've cooked with just about every mainstream fuel with the exception of the really large stick burners, but I absolutely love my pellet grill. I can get it over 900* if I wanted to for direct searing or go low enough to cold smoke.
I still have a gasser flat-top outside to do Japanese steak style cooks, eggs etc, but that's my only gas cooker now.
So now that I have sufficiently not answered your question, if you are set on gas, I can +1 Weber as I had one for well over a decade, and it was a tank.
