The R39M WRTC-2010 team used the Olympus DM-420. It worked great for recording 
each radio on a separate channel, but it can't quite do the length that you 
need. I don't have it anymore, so I can't quote the exact specs. It easily met 
the WRTC requirement of at least 24 hours on a single file, and a single set of 
alkaline batteries.

It was $150 at Best Buy, but you can do a lot better on the internet.
