+1 - I just got a couple (thanks, Vinnie!) and even though I am much less experienced than many here, there was no question about the tonal differences made available by the two that I got, on both electric and acoustic. I've only just started to noodle with them, but for the price of a pack of strings, they really add something notable to one's tone kit. So, re the question of cost/value, in the case of the V-pick I'd have to say it clearly falls on the side of the V.
Interesting sound, btw - smooth, fat, less bright than a thinner pick (it seems that this tendency is generally true of thicker picks from my experience). I was surprised that I felt comfortable playing with what is for me such a thick pick. I would imagine that experienced players would appreciate finer points than I.
