They are nice machines however when I was in the market I ended up getting a Korg D1600 mkII.

8 simultaneous inputs at 16 bit non compressed audio. It will cost you about a grand.

The korg recorders also come with the added advantage of having http://www.korgstudios.com/forum/ as s support forum. I have just been made a mod there and they are a really nice and knowledgeable bunch.

If you want something a little flashier their are also the XD series by Korg (16 and 32 track models)
