I passed on two of these for $10 last year at a goodwill thrift store. I almost bought them just because. But my rational side said I already have two good LCD's on my machine and I couldn't justify paying $10 on older screens just to get an Apple logo.
So... I guess that means not worth $5 each to me.
But, if it's what you really want, and it's worth the money for you, then it's really your decision.
I'm not going to bad talk them.
