Lots of good advice here.

The Edirol is certainly useful for workshops and rehearsals; it's really an amazingly compact machine.

Other things you might consider is investing in a set of high quality headphones so you can really hear what you are editing. We use AKG K271. Alternatively you could invest in a set of speakers instead of listening to whatever the MAC has; we use a pair of KRK VXT4 which sound pretty much like what was recorded without adding extra base, treble, or whatever your favorite set of stereo speakers might add. It's good to know what the recording sounds like before trying to edit it to sound different...

We also ending up investing in a set of studio mics such as the Audio-Technica 4033 for voice, and AKG C-534 EB for instruments.
