P.S. Ocean Vapor has the cheapest Vamo kit. $52 total incl. the cheapest shipping, but it can take up to a month to arrive if you use the cheapest shipping option. However, the customer service there is terrible. So if you order, make sure there's no Chinese holidays (which they quit working completely for and don't ship anything out) and also make sure you're not going to want to cancel (and if you ARE going to cancel or might, at least make sure you use PayPal, because Paypal saved my .... with them and refunded my money... they tried to scam me by sending me a private email promising they would cancel my order, but leaving a message in Paypal's dispute center that they had shipped the item. Fortunately, they screwed with the WRONG person... I'm an IT major in college. I sent in the copied text of their email along with the headers that proved it came from their IP. When Ebay and Paypal saw THAT, they IMMEDIATELY refunded my money even though the seller didn't even have the cash in their bank account, and charged it to the seller's account for when ever they do get money. Evidently the seller was unaware of this and still shipped the Vamo kit. So I'm getting it free.

Take that, suckers! LOL.
Anyways, if you want to be a bit safer, Zainy also sells the same kit for a little bit more, around $60 total. But they do same day shipping and their customer service is extremely quick to respond, friendly, and quick to resolve disputes. However, I think out of everything as far as customer service goes I would recommend the Vape-Pro. I'm sorry, but I have yet to see anyone beat the customer service offered by Totally Wicked. They will do practically ANYTHING to make sure you are able to enjoy their products to the fullest, even if it means sending you free product (I couldn't get started with the drip style atomizers that came with my Torpedo, and on top of that I ordered clearomizers that were for advanced users and required pretty sophisticated break down and a syringe to fill (CE2 XLs for the curious... yeah they are old, they were also very cheap on clearance, LOL), so they sent me a free $6 clearomizer, then sent me a free adapter when they realized they sent me the wrong kind of clearomizer... total of $10 in free product just because I was an idiot that couldn't drip right or select the right clearomizer, LOL. They even told me to refuse the clearomizer shipment that I ordered and just wait on what they sent me for free, but I didn't out of good conscience, considering they sent me more value in free product than what I actually spent on what I bought. I had even bought the Torpedo kit at a 50% discount. So yeeeeeeah... that was my start with an APV, LOL. Prior to that I had been using a Titan Tank (e-cig). What's funny is now I can use those drip atomizers... the whole problem all along was the kind of dropper I was using made the drops of liquid too big for the atty. If I use the squeeze bottle tips though they make the perfect sized drops. I didn't think anything of it because it was one of THEIR droppers... and they only asked if I was using their fluid. :-/ Ah well, they did make one heck of a dedicated customer for life...
Yeah, I'm a TW fan girl, hahaha.
Anyways, I hope this little story of mine is helpful to you. I know we tend to get so caught up on prices and all that, we forget to check things like warranties and customer service. Also... quality of product. Make sure whatever you get is almost bullet-proof. Also try to make sure there's as few jointed parts as possible and the body is mostly one molded piece. Right now you may not be able to do it, but eventually you will be able to look at pics and tell by the pic if it's a quality device or not just by the quality of its build. NO ONE takes extra TLC with the design and doesn't make an inside to match. And since warranties are generally anywhere from 6 mo. to a year, you definitely want to try to get something that is going to last a long time. And you're going to drop it. *sigh* You just are, accept it, LOL. My biggest mistake is getting mine lost in my lap and then getting up to look for it and... *clatter* LOL happens every time.
