Well, I bought it today! RB-67 with eye level finder, 127 and 90mm lenses, and a 120 back. I already fixed the back; very simple fix wasn't really "broken" at all. Took it apart and found the door was not contacting the lever that initiates the film advance dial/stop system. Turned out to be nothing more than a missing screw for the top cover that was allowing the door to slide under the lever.
It's got it's share of battle scars but works flawlessly. For $175 I'm not complaining!
Thanks again everyone for the replies. Now I have to buy some film for it...
