Hi Diane!- I sure wouldn't buy another UMAX, if it is less than 5 years old they should support it. I like Microteks, especially the interface, I just bought a new one, it is a Microtek Scanmaker V6usl, 36-bit 600x1200 Dpi, Usb/scsi Interface, Pc/mac, Flatbed Scanner. They go for about $120 on the web. The include the SCSI card, SCSI is faster than USB, USB is (a lot) faster than parallel.
