Hey,
 
I currently have a 901 and a smoke 51, and looking to get the ego or riva. But i keep on hearing that 5v and up is the way to go. Can somone tell the pro's and con's of them compaired to the 3.5v PV? And a good model to start out on myself. Perferably a reliable and good for a newbie to them.
 
Thanks
Thump
