Well, this isn't the time of year to buy bike stuff on ebay, it's the time to sell it. Seems to me that the best time of year to buy is Jan- Feb, after everyone's spent their Xmas load but before everyone remembers they have a bike in the garage and might like to ride it now that the weather's getting warmer.
Ebay works well for the buyer if you're patient. Seems like most everything comes up a few times a year, and if you wait and lurk, you can get a good price. Also, any bid before the last fifteen seconds or so is too early. I've recently picked up a Phil Woods track hub with cog and lockring for 70$ and a Var 30 Bottom bracket remover for 40$, both of which I'd call exceptional deals.
