Doesn't sound like a bad deal, but you can always make an offer.
If the rest of the components turned out to be ****, you'd still have lots of nice parts to sell. And assuming they're in good condition, I would think you could still profit (if that's what your goin for), but I would still make an offer. I don't know anything about Nishiki frames though. I know that C-Record components can go for quite a bit in good condition.
