Hello David, i too am from Maine!
what area are you from, if you don't mind me asking?
i personally never heard of refilling butane with propane, but i suppose if they make a product for it, it must be ok. as for the method, i couldn't tell you. there are some videos on the amazon link you supplied, perhaps those may shed some light.
