WTB- Scanner

Not as simple as the title states, though.

I'm looking for a specific kind of scanner. As it is now, I can only find one model that matches what I'm looking for.
-In short, it's a flatbed scanner with the slide mechanism (like all flatbeds) but is about half the size, for 4x6 photos.
-Only matching product so far- the HP Photo Scanner 1000.
-MUST have the same kind of mechanism as a full sized flatbed (not the ones you swipe over a page, or you feed the page through)
-If you find a different model I don't care about the connector type, interface, if it has the power cable, scratched, faded, poor image, etc.

Looking to get two of them, hopefully matching units.
