UMAX Vista S8
The UMAX VISTA series can use the [much better] MagicScan. But if you want, you can run the bundled VistaScan software. Envisions ENV8800S is a rebadged VISTA S8.

If you are installing your UMAX scanner without the "UDS-11" card, you can choose to install MagicScan / VistaScan using the Adaptec WinASPI layer.
