Pretty OT: Used cameras?

[makoti]

I'm looking for a used camera, specifically an Olympus/OM Systems body. OM-1 or maybe the older M-1 Mark iii.

Where do you guys go to look for a used camera? I'm on Fred Miranda, looking at the Ebay Oly Outlet, and MPB. Other ideas? Places you've used?
I looked on Craigslist, and actually found one, but the pictures I got were pretty fuzzy and seems to me like it had been dropped (nice nick in a place that probably shouldn't get nicked).
