8 3/4 Price? Sure Grip Unit Price?

I think it's a regional thing. I've seen them around here for as little as 100 for a bare housing to as much as 500 for a bare housing. Just no rhyme or reason.
RRR is correct (for once... LOL). I would have paid any amount for one down here in S. Texas, there are almost none at all. Most are far, far away (shipping costs).
