Can you tell what type of suregrip this is?

I've noticed lately a lot of guys seem to think these things have turned into gold. Look on e-bay if you want a good laugh

BTW: Dr. Diff does not have the $400 clutch type on stock and says he doesn't know when or if he'll ever get anymore. That was the word as of a couple weeks ago when I talked to him. He does have other units that go for about $600

Are they on backorder? Or is there some other issue why he may not get any more of them?
