I'm looking for a dual-tank auto-switch propane regulator, but I'm not exactly comfortable buying things I can't see & touch first. Any recommendations for a supplier? RV supply stores seem to jack things up 100% above what they should go for....
Anything I should look for to identify a "good" unit? I guess I'm looking for something like this:
