there's a guy in the classifieds selling off a bunch of stuff b/c of a divorce (too bad!), including a bunch of RNC's for $135 each - get 'em! - and a furman headphone system -- you might want that, too.

One thing I saw on re-reading your post was that you are planning to mix outside the box -- you will definitely need reverbs -- he's got a Kurzweil rumour for $450 and I would grab that as well.
