Zoom H2 prtable stereo digital recorder. Reords wav and mp3 formats to an SD(HC) card. Makes it easy to drag audio into your editors. I use it all the time to collect ambients while in the field. You can set it to 2 different 2 channel stereo configurations (90 or 120 degree) or run 4 channel surround (2 separate stereo files). There are a couple aplications out there that can convert this to a single 5.1 surround file. It runs about $165.

I have found that most of the negative reviews are from people that did not take the time to learn how to make it work. It does have a learning curve to it. Have had mine for most of a year and still looks new but I try to take care of my "toys".
Life is not a guided tour nor a destination.
It is a journey. Take the time to enjoy your family, friends and surroundings.
Build memories. Share experiences. Travel at sight speed not light speed. (C)
