I like AB cause I've heard more positive than negative about their disputes / new vendor scams, though with the PM leak, I am thinking about maybe looking to other markets to check out.
I've tried dream, and it seems like a wasteland. Vendors don't reply to product inquiries, heard support is non-existant. Haven't been to Valhalla but when I heard about it, it's usually in a bad tone about support or bugs similar to AB (I believe).
I will still use AB for what I always have until they turn off their servers, but would like to expand my horizons, what markets do you guys suggest to use?
EDIT** I am stateside so looking for domestic, I fear customs.
Hansa is my favorite marketplace. Great functionality and awesome customer support.
