I Didn't Either, I had my V3 on order when Adam Posted news about the V4, he did give me the option to have the V3 in 2 weeks or wait 3 - 4 months for the V4, and being in need of a good powder thrower, i went for the V3, well how much quicker can the new one be?
My V3 is fast but when it throws 1Gr under, it seems to take the trickler a while to finish off.
Like i said i have only seen youtube videos. But it does look damn fast.
I think i will be jealous of the V4.
