I have a couple bags of them, but because I was always pulling the boards 
to 'clean' and re-seat, it wasn't worth arsing with.

Back home (NZ) I have just a single twin-cab 4/470 right now, and three 
triple-cab 4/260s. In the US I have a pair of 4/470s (one of them with an 
nCUBE2 controller), a 4/670MP and a racked 4/280, as well as a pretty big 
supply of spare VME boards (thank you to Dan whom I got them from).

I just ended up pulling all the screws and stashing them. That being said, 
I agree with your assessment... I guess I'm just too lazy. What a horrid 
reason.
