I found one on amazon. the seller contacted me and said he had syncing issues using a mac. He did not test on a PC. he specifically said the transfer time would take really long for audio files. he was using the standard firmware though, I intend to rockbox it. think it's a good choice? Only 40 bucks
I have a H10 (bought it for development only), and I never use it. Crap design, don't buy it. Rockbox runs fine, but the SW can't make up for the stupid hardware design ;)
