Hi I've had great results recording piano and classical chamber music with a Sony Hi-MD Minidisc recorder and some good binaural unpowered mics. However, the transfer rates are so slow to the computer and the whole technology just seems outdated in light of cheap flash based devices.

Having said that, what are some portable rechargeable-battery powered flash (or even hard drive) based recording devices? I see a lot of voice recorders, but are those going to have the same recording quality and noise isolation as the MD recorders did? Im just worried about noisy mic inputs, which for voice recording might not matter.

Im talking in the $200-$300 ballpark, just for reference. Where do I go after the going-extinct MD?
