I have that exact model that I purchased at my local HD store. This model seems to be better made than the one at Wal-Mart. It may be the fact that there is more framing involved with the two doors that made if feel sturdier.
Have used it a couple of times now. I did a chicken where I got the temps to 350 for a few hours and also a beef roast and fatty with temps holding at 240 for 6+ hours.
I did replace the charcoal pan with the wok pan pictured below. I got this one at Lowes. I did have to cut the "handles" down a small amount to get it to slide in and out like I wanted. I used my Dremel and sliced about a 1/4" off of each handle lengthwise. First burn was at 240 for 6 hours and I can see no damage (maybe some slight warpage). I had zero issue with the fire choking out at the ash was able to fall through and collect in the bottom of the unit. You could probably put 10# of charcoal in this pan.
I liked the double door as well as I can tend to the fire and water without losing all of the heat while doing so.
You will not be able to do lots of meat at one time but if you are tight for space it will store much easier than a SnP.
I do plan a major modification to mine in the next couple of weeks. Will post pics if it works like I hope.
