I've bought juice from revolvercig, freedomsmokeusa and vaporrenew.
Revolver - very similar to dekang from what I've heard. Great throat hit, flavors range from okay to very good, good prices.
Freedom Smoke USA - tons of flavors. Good throat hit, great flavors if you let them age a week or two, crappy flavors if you don't let them age, good prices, little bitty sample bottles, good prices. On the down side, a lot of their premixed flavors are only available in a PG/VG mix unless you do a special order, and I really hate VG over a small percentage.
Vapor Renew - AMAZING flavors, TONS of options, GREAT prices, absolutely no throat hit. I ordered medium throat hit, and got nothing. Sadly, this is a deal breaker for me. No throat-hit = no satisfaction. If you ordered 100% PG and harsh throat hit, it might be okay.
