Sorry but neither of the envy’s are rare. There are a lot of them out there.
I have a DV8. Well it’s on it’s way back to me soon. Mine is the one that Extremespin.com used for their online store photo. It Belonged to Tommy Gun (aka Kyle).
Not a Tank, but I had both a purple and a blue Bare Bones by Diss Kings. I loved those yoyos.
I feel like there must have been more Grind Machine 2s… Well, 2.2s, I guess. The first version was a disaster. I do have a fairly uncommon version of it though. I believe it’s known as the Russian release. The champagne gold color, it was the first of the 2.2s released.
