I have a Umax Astra 4000U. Another Scanner Umax abandoned for OSX. The scanner is still current on their website though.

SANE doesn't have drivers for this model though.

I'm stuck because I can't really replace it. It's and 11x14 scanner and no one has a model that can handle that paper size without spending a fortune!

As a video professional I used to recommend UMAX for scanning for video graphics departments. I now actively discourage the same departments from buying UMAX scanners. I hope I've cost tham THOUSANDS of dollars for their BAD customer relations and internal policies.
