The one lists the screen for $86, the other has the cable for $89.95 (less a $20 discount). It doesn't make sense that the cable would cost as much as the screen.

I just sent an email to the vendor I found on eBay that looks like it might be the right thing. If they say it's the right one for my model, I'll ask them to point me to some online documentation from the manufacturer to confirm it. Basically, I'll ask them how they know it's the right one.
