Let me be the first to say "build a UDS."
Seriously, I have relegated my modded CG to grill duty. It burns too much fuel and is a pain to maintain temps where you want them. I switched to a UDS back in the Spring and haven't looked back.
There are some other cookers that do better than the CG that cost less than $1000.00. A WSM, a BGE, the Bubba Keg, the Big Steel Keg, a Weber kettle, are a few.
