Never used ours yet either. Since most of my grilling is charcoal, and carry a weberQ for that rare occasion I need gas it probably will never get used. I would like to remove the grill and turn that into a storage drawer.
As for the little green 1lb tanks, years ago I got a fitting from harbor freight that allows me to refill them off my 30lb'er. Not sure if it's still available or not.
