Devolve... They had a booth at the NWTF convention in Nashville this year and Jim Clay, the founder of Perfection Calls, was manning the booth, along with some other folks...

The company used to be based at Jim's home in Winchester, Va. Try a Google search.... If you can't contact them that way, get in touch with NWTF and ask them for a list of exhibitors...They must have the addy for Perfection...
