Nothing with a digital read out, but I know Kalamazoo Vapor Shop sells a VV box mod for $50 new. They make solid units. I'm using their Big Kazoo until my ProVari arrives.
I believe it goes all the way up to 7.4 volts.
They are out of stock right now, but I know James (the owner) regularly makes mods. He's famous for those Kazoos
