I know this has been answered again and again, but I'm new to smoking and would like to offer a newbie's view:
I started on a little $30 grill by indirect cooking and bought myself a
WSM for Christmas last year. I love it! I did a ton of research before I bought that particular model (see
http://www.virtualweberbullet.com/).
Here's what I found from my few months of using the
WSM:
1) Natural fuel (wood, coal, etc) gives meat a more natural taste.
2) I get much fewer flare ups when grilling over natural fuel than I do with gas.
3) By using natural fuel, I don't need to haul propane around, I just grab wood from the camp-fire pile.
4) I feel like my food has more character, and fuller flavor, when grilled or smoked over natural fuel.
5) The
WSM can be used as a grill or a smoker. It's constructed very well, it's fairly cheap, and it's easy to throw in the trunk of any mid-sized car.
6) Wood smoking may take more skill to get a great product, but practicing that is a great way to spend some time. (Same goes for home-brewing)
7) Wood smoke smells like heaven.
