Refilling 16 oz propane bottle off a 20# tank

All things considered, especially the fact that a leaky propane bottle (regardless of size) can ruin a camping trip, I'd almost just buy this and call it done. It is small enough that it can be kept inside, unlike a 20# cylinder.

This is not to say that the 1 pound bottles are not useful. As something for emergencies, they have their uses. I just don't trust them to be constantly reused.
