It's times like this that it's good to be on a local "nerd" mailing list. Join a Linux, or Free Unix or Computer Hooby mailing list for your area. Then ask. I've gotten many things for a beer, or a six-pack. In fact, I'm picking up a hub with aui and bnc tomorrow that I got from asking my local linux group. In fact, I could have had 3, plus all the bnc cabling I could ever need if I wanted.
eBay is fantastic, but yeah, items that should never cost you more than $10 in the real world, always end up costing $40 including s&h. I admit, sometimes I bid anyway. Argh!
