Hi great information here but I am still usure what to get: My main objective is a digital recorder to capture field audio - highest kbps; minimal compression; manual on the fly gain control as well as AGC; 1/8' mic input (power plug in or just line in as my mic is self powered); analog & optical out, and most important it has to work with mac OSX for both up and download; preferably not only real time via analog headphone out. My budget is under US$400. I will compromise for battery capacity, size, weight, design, LP capabilites and playback features. What I need is a hi quality digital recorder in the above price range. According to what I read here, Sony HI-MD, although answers most of my criteria is not Mac friendly and in general I do not appreciate products that go out of their way to impose limitations on their owners, be it due to copyright issues, buggy proprietary SW or market competition. I'd go with a HDD, minidisc, or flash as long as they provide hi quality audio, operation versatility and Mac compatibility. What could be a nice bonus is if that yet to be discovered recorder will be able to UL/ DL any media/ data files form/ to my Mac. Your suggestion are appreciated. Thanks
