Thanks for all of the responses.

I keep the cylinder inside the kegerator,(an older Kenmore), and I never open the door, except to clean the lines and swap out the kegs.

For my purposes, unless I get a sweet deal on one, it appears as if a dual-guage isn't worth it.

When the time comes, I think that I'll stick with a single gauge and purchase a spare CO2 bottle.
