re: What will be your next grill/smoker purchase?

I agree with you on this, and have this to add. I have gone full circle, starting with a kettle some 30 years ago, and added a WSM about 12 years ago. Always had a gasser for the reason you listed. Ventured into offset smokers and cookers, vertical offset, kamado cooking that started with a small one and now own a primo Oval XL for three years which resulted in the sale of the WSM, small kamado and the two offsets. Just about 2 months ago, dusted off the performer that was in storage and have really enjoyed cooking on it due to the simplicity and convenience. There really is nothing quite close to it. I too have the slow and sear and fan attachments. Needless to say, I will be placing my Primo Oval XL up for sale, along with all the attachments and two tables, priced to go. It's an outstanding cooker, but it's just the wife and I now, not much tailgating or big football parties, so no need for the grill real estate anymore.

ETA: to th OP, go Weber kettle, 22" or 26" and you tube/ google for more tips and techniques!
