Thanks, Rob, that's more along the lines of what I'm looking for. What you're talking about is fine, but I don't quite understand how you'd change the temperature while in the shower. I'm also not sure how you'd get it to the temperature you set on a normal shower control, just throw it all the way to the hottest setting? I'm not sure how well that works. I'd rather know that what was coming out of the showerhead was the exact temp I wanted.

Phew! The prices for those iodigital products sure ain't cheap! Oh well, I knew they'd be expensive, I was just looking for some ideas for a possible future install. Thanks again!
