I just bought a VV Splash by Shan, and it should be here tomorrow. I liked the formfactor, the voltmeter built in, and the coolfactor. If you can find one through the classifieds, expect it to only set you back about $65 shipped (That's what I paid). I checked their site daily for a couple weeks, and NEVER saw any new for sale.
If you want to consider a tubemod, I personally fell in love with the Notcig products (I own a Buzz Pro, but the INfinity is very nice also, and a little easier on the pocketboot, with all the same circuitry)
