Thanks again to whoever recommended Dawson Jones (Dr Liv?) - I have a terrible memory when it comes to that.
Anyway, great shop, great selection, great prices, great employees. Had a minor snafu with my last purchase, which they fixed immediately, no questions or hassles - done and done. Made it right.
If you're in the ATL area and need a mannequin, z-racks, whatever - this is the place, and they're open Saturday's which - for me - beats Stamps.
