...cost Vs performance is a relative thing and kinda subjective...I spent around 100bux a week on funkarettes so, even a Darwin is only a couple of weeks of my previous smoking budget...FOR MYSELF, I wouldn't buy a 100+dollar PV because I don't need it and I started vaping to save money, not become a hobbyist...I started with a Riva and tired of having to change batts every 4hrs to maintain consistency of the vape...I got an E-Power for 55bucks with a bunch of freebies from crystalclearvaping.com...then for Christmas, I was lucky enough to have been gifted with an Evercool box mod...these can be bought for around the same money as an E-Power...would I ever buy a GLV or Buzz or any of the other higher end mods, probably not since, FOR ME, they are not needed or required...I know some folks complain about all the choices BUT, I submit to them, how many choices are there in the funkarette world...including all the brands/styles/flavs of funkies, cigar, pipes, it has to be in the thousands...decide what you want in terms of performance and after that, find what trips your trigger...........

p.s. a switch for an E-Power can be had for under 10bux and batts for around 5...for the
equivalent batt power in an Ego/Riva/Kgo, you would be spending 18-20bux...
