I like good smoked meats - pork (ribs or loin), chicken and turkey, heck just about anything is tasty if properly smoked.
I'd struggled with getting good results until my sister gave me one of these for Christmas a while back:
It's close to fool proof - you put in the prepped meat, put some water in the bottom pan, add some wood chips, set the desired cook temp and time, and push start. About once an hour I go and add some more wood chips - other than that just let it go until it's done.
Most stuff I smoke at between 200F and 220F, and between 3 and 6 hours. Have a good meat thermometer on hand just to make sure it's properly (i.e. safe) when you're done.
