How difficult will it be to get good results on one of these? How much work is your buddy likely to put into it to make it work?
What is the chance he'll give it a shot and give up because it just doesn't produce spectacular results?
What about a Weber kettle? They're very versatile and you can get great results grilling and using the indirect method. With proper technique you can smoke on one too. They're less expensive new and more available on CL.
