Just seeing this Herb, which route did you go with?
I've made a couple ugly drum smokers, just basic ones but it is definitely hard to control the temperature with them.
I've also had a few electric smokers and now a pellet grill. Yes, I know pellet grills aren't your typical smoker but they're super easy and control nicely.
I have the Silverback by Grilla Grill, absolutely love the company and the owner has taken calls over the weekend to help people with issues, says a lot.
For something smaller look at their Kong at Grilla Grills.
