No experience with those. It'll probably work.
My only comment is I used one of those little iron boxes for the wood chips on my gas grill a few times. Didn't work worth diddle because the chips burned up too fast and didn't put out much smoke.
If they solved that, you should be OK.
BTW, you know they have electric El Cheapo Brinkmanns, right? Even the "Gourmet" model is available in electric. Even easier than propane.
