I like disposable pans most of the time. The dollar store has a variety of sizes. For some things I prefer a more sturdy pan, and have accumulated some that are dedicated to smoking, camping, grilling, etc.
I have a large Action Packer with a lid that locks down firmly. I keep my smoking accessories, tongs, pans, rib racks, and assorted bits and pieces in it .Stored under a prep table on the deck where the smoker is, I keep it segregated from our regular kitchen stuff. The first time you grab a pan to use in the smoker, and your wife discovers you are using her grandmother's favorite heirloom special family treasure, you will appreciate having your own.
