What's an appropriate programmer for the AVR chip and interface on the board? (Appropriate ... and not too expensive, of course.) I'm running Windows. Prefer to use my laptop (Vista) with USB ports and a USB to RS232 dongle available. Also have an XP PC with real serial ports.

I'm building the DDS board now. Built another for a friend recently and it worked fine. This one I'll try some programming on. I'm relatively new to AVR programming although I did add some code to the Butterfly DDS controller software by Steve Weber some time ago. I gotta be retrained ...
