-- Cheap NiMH's on eBay (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=3570)

you can get some good deals in NiMH batteries on eBay. Just search for 'nimh' and you get a list of about 100 or so aucitons. I regularly see 4x AAA's go for $5.00 (plus 2 or 3 dollars shipping). worth a look..
