I've been lurking on the forums for a few days and have found a TON of helpful information. Almost to the point of being overwhelming. After lots of reading and watching quite a few youtube videos I have somewhat narrowed down what I'm looking for. I'd like to buy a PV that is just the two piece cartomizer and battery. The 510 seems to get decent reviews but I believe I've seen more than one brand of 510, and I don't think some of them were just the two piece, so I'm not certain which one to buy? Can anyone provide a link to the best model with the best price currently available? Another thing that I'd like to have is a drip tip. I've seen these in the youtube videos. Is this something that is standard on 510's or would I have to buy a different tip in order to fill the cartomizer through the tip? Thanks to all you guys and girls who have posted so much helpful info on here. I'm looking forward to getting started.
