I got my SVD through a coop for $56 . Build quality is phenomal and looks more interesting than the Vamo. It is a bit longer though. My buttons are oriented correctly with the screen (i.e. + button is above the screen.) Some peoples' arent. I personally like the LED button that changes from green to yellow to red according to battery charge. The only thing I don't like is the way cartos sound in dual 18350 mode ( Sounds like a lawn sprinkler because of the firing frequency). The screen is not as good as the Vamos. Overall its a great device if you can dish out the money for it. The 2 complete iClear 30s with 3 additional heads is a good edition to the package.
