B3D makes their filament in Florida but call it "handmade" I've never had the guts to try it.

Ebay is normally just reselling the Chinese stuff, that normally happens in California or sometimes in lower NY/upper NJ. I really don't have a problem with it because I don't have time sensitive projects, but I understand someone willing to pay more and be sensitive about quality when you get a project you NEED to complete ASAP, or need to print a decent number of successful parts in a row for a deadline.
