My first thought was Ardunio (sp) as a solution. I began following the Brewtroller and thought it would be perfect as I have not programmed anything for 20 years. Then the addition of relays, display, etc. got me thinking of something less complicated (but less capable) that could be PC controlled. Again, the programming would be a time suck. I have way too many of those.
I plan on ordering a Brewtroller as soon as I get back from a ski trip I am on. Also looking at a pair of temp sensors from stirplates.com (now brewershardware.com?).
Thanks for everyone's input.
