In case anyone wants to try smoking with a charcoal kettle grill or doesn't have the funds for a purpose-made smoker...
I use the 2x2 snake method and find that I hold 195 with the vents shut (top and bottom) to a pencil diameter sized opening. Every 1/8" increment opening them results in an increase of about 15 degrees (which takes about 15 minutes). Below is my setup, it's just two rows of briquettes around the bottom grate with another row of two stacked on top of it. Basically it burns like a fuse, slower and way cooler than lighting the entire batch. Don't let the wood chunks touch otherwise they will ignite each other and light the "snake" in the middle and things will get hot. Don't worry about soaking the wood chips, you're not letting them have enough oxygen to flame up and they will only smolder.
I also put a put an aluminum pan of water in the middle which regulates the temp and helps keep meat moist. To light it I have one of those wax fire starter cubes at the beginning which you can see in the picture if you look. What I have set up in the picture below will run over 10 hours (I think I was doing a really big brisket here), I have extra coals at the end because the last hour I open the vents all the way and increase the heat to crust over the sauce I baste with.
Just thought in case anyone was curious or limited by budget and still wanted to try smoking meat. Smokers are nice, but you can get restaurant-quality BBQ with very little cost and almost no complexity.
