I would go with a UDS. You might not be able to get 25 racks of ribs on it but you can get quite a few. Plus they are easy to build and inexpensive. They are also on Craigslist pretty often if you just want to buy one.
Don't forget though that it is the cook not the cooker. We all like to play with new toys, but you can confuse yourself by having too many different things going on.
