My sister in law is looking to surprise her wife with a good but inexpensive smoker. I suppose decent quality and ease of use are the most important features. It's just the two of them, though they are looking to add a child or two eventually. They ocassionally host small parties, so it should have a reasonable amount of capacity. They have natural gas available, but I don't know if there is a preference for wood, LP, or natural gas. Anyhow, does anyone have some recommendations? Thanks!
