For a low end Bullet type, I wouldn't overlook the Char-Broil electric H20 smoker. IMHO it's hard to beat, especially for a novice Q'er. They have an electric thermostatic control that eliminates the need to fool around with vent's & fuel to control temp's. AKA Lazy-Q. Although most people who Q find the fooling with fuel & temp's part of the fun.
I've had 2 of these unit's, and while the temp control may not be as precise as with a non-electric type unit, they can put out some pretty mean Q. They are a good entry level unit, and a few more experienced Q'er's even like them.
The best part is they only cost about $70.00 at H.D., which leaves a lot of "wiggle room" in the wallet should one decide to upgrade later. And they alway's come in handy after you have bought an upgraded model as well
. Just my $.02. What ever you decide on I'm sure you'll have lot's of fun with it, and lot's of good Q. Good luck. YB2
