Booch, where would you be using this? If you are going to put it in the back yard, I would look in to a Weber or Vermont Castings. The Keg-a-que looks neat but it feel kinda gimmicky to me.
HERE is a link to Keg-a-Que if you havent seen it yet. 8)
Looks more gimicky than functional. Saw a yellow orb Q at World Market for $20.00. Looked kind of neat but would only hold less than 10 bricketts. Go for the Smokey Joe if you're looking for a portable. My .02.
