Thanks. The problem is that the guy who owned it claims that it was stored in temp/humidity controlled enviroment, but he really can't document it. From what I've seen of the stuff, it appears to be in good shape (some of it in OWC) but without that documentation, HDH passed on it.
Which, and not to digress, is part of the reason that I buy stuff from HDH. I pay a bit more at times to get stuff through them, but I'm very confident of condition, storage, etc.
