Here's a nice little isolation transformer I've used a bit. They're easy to solder down to a perf-board. Only 4 pins are wired, but the other pins lend to mechanical stability. The price is good and they're handy to just have around for general use.

I know this is not an ideal situation because of the potential ground loop. I like to do things right and put some kind of isolation in the line. Radio Shack used to sell a small transformer that was perfect for this but I can't find them anymore. Anyone got an idea for a sub? Maybe some type of opto circuit might be the way to go. I don't need something pre-made, homebrew is fine.
