Wow...you've been stuck on this "analysis paralysis" for a long time! haha I could have sworn a couple months back you had decided 100% on the Shirley 24x36.
Anyways, if you really want to dip your toes in gently rather than taking the plunge I'd recommend going with the Old Country Pecos. It's an "entry level" offset smoker which is designed OK, but it does have very thin metal. For $400 you can really get a sense of whether or not stickburning is something you'd like in general. The Pecos has it's issues as do just about all smokers, but it should give you a solid taste of what it's like to tend a fire.
You can find them at Academy Sports. It doesn't look like there are any in Atlanta, but there are a few which are within a reasonable driving distance.
As others have mentioned the Shirley 24x36 is a solid cooker which will retain it's value very well. If you were to go that route now and end up not liking tending fire I'm sure you'd be able to recoup your investment.
Good luck.
