Re: Universal IR remote controller

I bought an RCA RCU807 unit from overstock.com. This unit has a learn mode
that copies command from an existing remote and cost $25. Hope that helps.
The high end product is the sunwave unit. It has not only learn and macro
(combined commands for multiple devices) but is PC programmable. Check it
out at http://www.remotecentral.com
