BMV. Was my first vendor as well. I bought around 20 or so juices, loved one (hypermint), really liked three and still use them (vanilla mint, peppermint, snow), thought a few we're decent (honeysuckle tobacco, smooth, cherry ice, mojito, Jamaican rum, big island drink, buttery nipple, and peach) and found several that were downright nasty, for which steeping did nothing to alleviate (robacco, robacco menthol, robacco cherry, Morley, cherry vanilla swirl, coffee n cream).
Cheap, yes. But I think you, like I, will spend a lot of money there trying to find a few decent ones you enjoy out of the lot. After BMV I have tried NLV and ecigexpress, bounty hunter at NLV and peach and premium tobacco at ECX. Bounty hunter I recommend trying if you haven't, not for everyone but worth a look if you can get your hands on it (cult following) and I didn't care for ECX's premium tobacco, too peanuty for my taste. The peach was good, but very, very sweet to vape for long IMO.
After these I hit on HHV and loved, absolutely loved, every one I've tried, especially the naturally extracted tobaccos. Just ordered more in fact, Gandalf, Darkhorse, serendipity, Shadowfax, Gollum, Oompa, angels kiss, Cinful pear, dragons fire, heavenly tobacco, huntsman, all very, very good.
Is BMV worth a try? Sure it is, but don't waste too much time, effort, and money when great vendors are out there with just slightly higher price points, HHV, Vermilion River, Halo, many others that get great reviews that I haven't yet tried.
