I just found this old thread and thought I would ressurect it with some of my findings. I hope more of you add to this old thread, I'm sure there have been some new bargains since 2007.
I consider myself very fortunate in this category. I've always worked in post houses and when they get rid of stuff or upgrade, I'm right there waiting. I'm also a small local installer plus having friends or family giving you stuff is good too! Please keep in mind though that this happened over the course of 25 years, granted most of it in the last 15 but accumulative none-the-less. There was a lot more, this is just what I kept and still use regularly, all in perfect working order and in or near mint condition.
For my 2 channel system:
Sony A-7 DAT recorder, free from my brother-in-law
Akai 1722W Reel-to-reel tape deck, free from a post house I woked in back in the '80's (let's see, that would make me about...nevermind)
