hey pwoods! for some reason i've been a member for over 2 weeks, but still can't comment on posts. Saw your inquiry on whether to go adjustable rig or woo.
I just bought the adjustable rig customer combo, and it's all you need and more. You will want to add extra racks, extender, maybe even a larger stone for pizza's. But what tom gives you with that kit is a great start.
I have the adjustable rig, and the plate setter. I like both for different uses. Pizza I like having the plate setter in to block the scorching direct heat. A 1 butt or brisket cook, i use the plate setter. The rig gets used for elevated direct cooking, or when im cooking multiple butts and brisket
