No worries SmallBBQr, thanks for the input.
Freezing shouldn't be a problem, it only gets down to freezing 3 or 4 times a year here. Right now my available options are:
1) Buy a nozzle adapter and use Butane ($4/ea)
2) Buy an adapter and use a 20lbs. propane tank ($50/ea)
3) Use 1lbs. MAP/P gas canisters ($20/ea)
My Summit doesn't have the built in table, and I'd like to keep it easy to roll around, so I'd like to avoid option #2
For the trouble of importing the parts to refill a 1lbs propane tank from a larger tank, I might as well just import the Butane adapter and save myself the hassle of doing refills.
From what I've read so far, it seems like I'll need 2 adapters, one to go from Butane nozzle -> Lindel, and a second to go from Lindel -> Coleman style Propane. But I'm curious if anyone's found a single adapter that'd do the trick.
