Smokeless Image for cartomizers and batteries.
Value Vapors for attys, tanks, drip tips, drip shields, ect
Mt. Baker Vapor for liquid (and they have some 510 equipment)
Everything I've ordered from these three has been exactly what I expected, shipped on time and very well priced. Haven't had to use CS for any of them yet, but James Thompson from Mt. Baker Vapor is happy to respond promptly to any emails sent his way.
Mt. Baker Vapor is on the west coast. The others are in the center. All three have arrived to my door within three days of any order using standard USPS.
