They are all in very good condition! The G80-0441 is probably the rarest keyboard I own, but I can't use it, since it is a XT layout and US, too. Also it has no case or cable. Similarly with the G80-0530: I simply can't justify using the keycaps on another board, since they are almost mint.
I never had a chance to try one and when I look at the price, I'd rather spend that on another beam spring.
Yes, that's my rule too. I don't buy anything that isn't either collectible or nice to use. It just so happens that, even while following that rule, the quantity can get a little high..
