thank you for the replies. as for sound, i would probably prefer stereo for recording the ambient noise but am not 100% convinced that this is necessary. the audio will usually be accompanying still photos in a slideshow for the web on either a program called soundslides or using flash. as for recording times and compressed vs. uncompressed...i imagine i would record the whole time i am out shooting, which at times may be a couple of hours, though i will only end up using 4 or 5 minutes of audio in the end. am i correct in assuming that the old sony md players require you to upload audio files in real time to your computer, while the Hi-MD players allow some form of quick drag and drop? if so, it seems as if the MZ-NH700 you are suggesting would fit the bill for all that i am seeking and at a reasonable price as well. thank you very much for your help.
