Yeah, I bought one earlier this summer. Its my first venture into the world of smoking, so I probably cannot comment intelligently, but it seems to be a halfway decent unit. Surprisingly, I have been remarkably unsuccessful in finding anything online about the GrillPro vertical.....
I actually went into the store to buy a Brinkmann vertical unit, but after checking out the GrillPro, I liked that one a little more. The door closes a lot tighter, the unit itself is a little heavier....those are the only two things I can remember off the top of my head. Anyway, I smoked a 4 lb. brisket flat and 2 racks of baby backs this past weekend and everything seemed to turn out really well. The only complaint that I have about the unit is that I seem to have a lot of trouble maintaining temp. I usually start out around 200, but by the time I'm finished, I'm struggling to hit 175. So, I generally have to finish everything on my Ducane gas grill - which isn't a big deal, b/c my wife likes her ribs with some charred sauce on them.
I am actually on SMF this morning to investigate some mods to help increase the heat.
Hopefully this helps.....
