As a seller and collector, I'm interested in knowing where others do most of their diecast buying? After 20 years in the hobby and 8 years as a collector/seller I'd say my hunting and buying sources are fairly diverse with the largest % probably coming from retail mass market (although scoring anything remotely HTF has really gotten tough in my neck of the woods in recent years)

So...how about everyone else out there? Where are you shopping and buying these days? Ebay, other online, Hobby, mass retail, other?
