For 35 bucks + shipping you can get a Mya econo QT, 13 inches, adaptable to two hose if you want to, smoke likes a demon, comes with a carry cage and other extras. You can't go wrong with a Mya. Here's a link . . . http://www.southsmoke.com/pd-econo-mya-qt.cfm
I have this rig and it is awesome. Smokes like a dragon with his tail on fire. Easy to clean. Easy to store. Smoke happy.
