Can you tell what type of suregrip this is?

$500 and that's half of what they can be bought for? More like 2.5 times what a used SG actually sell for on the open market. You can buy a complete 3rd member with a decent gear set and clutch SG for in the $500 range.

Where is this seller performing his comedy act?

What a rip off. Looking for a sucker.
