To be upfront with you, I sell Yoders, so I'll spare you the big sales pitch.
The Wichita is a great offset smoker (I own one and love it still). If you're cooking in your backyard, it's hard to beat. Easy to control temp, great build quality, lifetime burnout warranty. Getting it Loaded with the HMS (Heat Management System) is the way to go IMO.
If on the other hand you were looking to compete. Go with the 24", which is the Kingman. You'll be glad to have the extra space.
As far as any options you want. Yoder will customize pretty much anything to your liking on their offset pits. So if you find something you'd like incorporated, let them know. They can and will do whatever you'd like to the pit so you are cooking on something you'll love.
Hopefully some other owners will chime in as well, as there are a lot of them out there.
