I've found that you almost (ALMOST) can't buy your hardware and juice from the same vendor and be satisfied with both. Seems to be a big downfall for most. :/ There is one exception though, vapor4life has pretty decent juice and their batts are OK, but their cartos are probably one of the best you can get. They supply KR808D-1 stuff, which is probably the second most popular model of e-cig users (510 is most likely #1) and the combo of their stuff together is just awesome.
