Smoked pork shoulder, first try.

I have a mastercraft electric smoker that has insulated walls. When the electronics went out I converted it to propane using an old side burner from a previous grill (never throw anything away!).
Check out smoking-meat.com for mant recipes, and smokingmeatforums.com for lots of tips.
I use the quicker higher temp method for pork butt 300 in the smoker until 165* then I wrap it in tinfoil and put it in the oven a 300* to a temp if 205*. Let it rest an hour and it falls apart! Usually takes about 6-7 hours depending on size.
Get a pan with a rack to put your meat on and keep the drippings from hitting the heat element. I use this.
