That grapple is an Anbo and it cost $3000. It came ready to hook up (they make them for whatever FEL you have). I already had the other set of lines there as my bucket is a 4-in-1.
There are cheaper alternatives and I haven't had a chance to see how handy it is yet. Maybe tomorrow?
The PVC with a cap sounds pretty interesting. I could put a couple up there. Maybe insulate one to keep a few beers, I mean pops cool.
