I have a smaller version of this one:
Masterbuilt 7 in 1 smoker/grill

It works very well and is easy to use and take care of . They also have a stainless steel version for $229 . I don't know about the model you asked about since I've never seen one , but I had a charcoal only smoker for a couple of years before I got the one I have now and I'll never own another one . Mine uses either charcoal or propane , I've done both in it but prefer the ease of use , cleanup , and controllability of propane . The unit performs flawlessly with both though and packs down into a fairly small bag for travel .

You may also want to look at electric smokers , they seem to have a larger variety of sizes . This one is fairly representative of the breed and probably the right size and price range for you:
20 lb. Electric smoker
