My advice? Don't do it. My first foray into smoking was a Charbroil American Gourmet from Walmart.

This thing had so many holes in it that needed to be plugged, and it leaked heat and smoke like a sin eve. I'm pretty sure I spent more in hardware mods to seal it and get better heat retention than I paid for the dang thing. And then, if I wanted to smoke something like a brisket or a couple of pork butts, I had to stay awake all night tending the thing. Much like a boat, selling it was the 2nd happiest day of my life.
Nope, save your money and get something of better quality that doesn't need constant attention.
