I ended up buying the CharGriller with the side fire box and I'm VERY happy with it. I found a couple online communities that like this smoker and found out some mods that improve it quite a bit. So far I've done chicken (marinated chicken breasts BBQ'd at 225°F up to an internal temp of 155°F are heaven), pork, and a beef roast. Mrs. yooper keeps buying expensive cuts of meat rather than the traditional BBQ cuts, so they've been a little too lean I think, especially the beef. I finally convinced her to order a Boston Butt and I'll be doing that this weekend. Haven't tried ribs yet.
The CharGriller is actually a better grill than my Weber kettle for regular grilling because of the adjustable fire grate and the cast iron food grate, so I haven't used my Weber since I got the CharGriller.
