I have a brinkman barrel like this:
I used to have an electric model and it finally dented, rusted, and died. The new one I have is the same thing but charcoal. It wouldn't have been my first choice, but my nephew bought it for me.
Smokers don't need to be fancy. Some guys will tell you that heavy steel or sidebox fires are the best way to smoke. Its BS. Two things are happening. There is heat to cook things and smoke to flavor things. The meat doesn't care if its in a cardboard box. It will taste the same. I had one of those fancy sideways barrel smokers with the side box and it made fantastic meat, but tending a mesquite fire for 12 hours isn't my idea of fun.
I agree that smoking huge chunks of meat aren't the best. I keep my cuts to 10 lbs or so. That also makes more surface area to absorb smoke.
Upsides to the one pictured above:
- multiple layers to hold lots of meat
- vertical arrangement means all the meat can have equal temps (sideways barrels tend to have hot and cool regions because of how the heat flows through left-to-right)
Downsides to the one above:
- difficult to access meat on the lower levels for inspection
- made of thinner steel so it tends to squish easily
- unless you have it in a pan, the top meat will drip on the bottom meat. That is fine, unless the top level is teriyaki salmon and the bottom level is butternut squash. Fishy squash. Ew.
In my opinion, the best way to do it right is to modify whatever you get if it doesn't suit. My first smoker was like this:
It did have hot and cold spots. The heat from the firebox came into the smoking chamber and rose right away. Hot spot on the right, cool spot on the left. I screwed some sheet steel inside it to make a "shutter" that I could bend up or down to direct the heat more centrally. The other thing I would do is install a gas burner in the box. Not only does that make lighting the fire easier, it means I can walk away from it for more than 30 minutes knowing it will maintain temperature even if the wood runs out for a bit.
Another tidbit. Don't worry about going nuts with lots of smoke. If you smoke (for instance) a brisket for 12 hours and you keep putting wood on it, you'll have a brisket that tastes entirely like smoke and nothing else. Just a few hours of smoke is brilliant.
Another thing. Invest in one of those remote digital meat thermometers. You can put the probe in and leave it there so you can monitor meat temps without opening things and repeatedly stabbing the meat.
And one last tidbit. You might want to consider some kind of chimney. The black smoker above was really good at one thing. Take a bundt pan (the kind with the hole in the middle) and put it on top of the chimney. Then take a mixing bowl just a little smaller than the bundt pan and put it on top. Smoke goes up through the bundt pan, hits the mixing bowl and condenses. When you're done, the condensate in the bundt pan is the best liquid smoke you've ever known.
