Hi,
I have an analog 8-track recorder which I use with digital recording software(Mac). The Mac accepts a stereo line-in from the 8-track. An 8-track digital should work in this fashion. You can mix 8 tracks down to two digital in your computer, then keep working on your computer.

There are advantages to analog as opposed to digital recording; analog is more forgiving when recording "hot" signals. You might be able to pick up an analog recorder for less money, if that's an issue.
