We have a booth from 2 years ago Internext in Vegas that is a great, simple booth. Can be used for 20 x 20 or smaller (pieces can be taken out and rotated), nothing fancy, but can do a lot with it. Here are some pics of it...we used it as two sides and had it lined down the middle of our space. It's already in Vegas in storage, so if you are interested, let me know.
