Sahara.. What you really need to do is really think about what result you want from your PV, you are right there are so many toys out there and it's hard to choose, but ultimately the best way to figure that out is make a list of what the requirements that would make you happy are.. Me personally I like my 510 and don't really need anything more at this point, my problem is I have one now in almost every color, but you know that is okay too because at least I know I have enough stuff for awhile.. Honestly though if I was to step up it would be ego, riva, or hello 16, that is what I would get for the hubbie and will when he decides to get back on the ecig wagon.. I hope that you can figure it out I know it's tough but have fun with it!!
