Recommend a Digital Recorder for...

...my wife to record cello lessons and playback at slower tempos. Would also need to record CDs to slow down as well. Is there something out there that could do this?

Try a Zoom H4n recorder. It has a built in phrase trainer that will slow down tempo to 50% of the original while not affecting the original pitch. It can handle several audio formats, has it's own built in stereo condenser microphones, and can handle mic, line and instrument level signals. Acts as a multitrack digital recorder.

You will want one yourself. Lots of guys on the forum are using these.

I don't own one but want one real real real real real bad.

That H4N looks cool, but maybe not cool for my techno-phobe wife. I'm hoping for something as easy to use as a cassette boombox, multitrack is not needed. A digital boombox would be perfect: built-in mic, decent sounding speakers, pitch control.

I think you underestimate her abilities. I mean, there is not another one out there like my wife. At least, that what she tells me.

how about the Zoom H2 ?

or the Edirol R-09

All easy to use and really do not require a tekno-mind

Thanks for the replies. We went with the Tascam DR-07 ($169 at GC).
