I am considering picking one up from a local shop.

Its got two Tascam cards loaded into it.
Are there adapters to connect TDIF to ADAT?

What would be a good deal on this mixer and are there any issues that would steer me away from this mixer?

I am looking into eventually getting a hard disk recorder. as opposed to my computer for a portable recording rig.

Has anyone used this board? How does it sound? Any cons?
