I've worked on Ramsas in 3 different places. I can't recall the model at the first two, but currently I am working on a WR-C4520. All 3 had one thing in common...crackling pots and faders. Someone mentioned maintenance earlier in this thread, which these boards probably were NOT maintained well, and that seems to be the big thing to watch out for, from my experience.
Avoid that (or work around it) and you should be able to get some decent work done. Still, I'd make sure I wasn't selling my firstborn to get one. It aint THAT good.
