"I should be looking at gas smokers too."
Gas creates water vapor when it burns, which interferes with the smoke doing what you want it to do to the meat.
Stick with electric, such as a Brinkman. They're really inexpensive.
If, however, you want to go fiddleless charcoal, and are willing to pay for it, go with a ceramic smoker, such as a Big Green Egg.
Castlekey has one of them. They are VERY precise, can hold a fire and exact temperature for hours, and provide an excellent end product.
But they are NOT cheap.
