My Two Cents:
I have the 1200U....great scanner. So much nicer than the $200-800 units we have at my office...faster, better color, better TWAIN drivers......
Only problem I can gripe, but it's my fault, is that the damn scanner is soo accurate, it picks up every little speck of dirt at higher resoloutions.
When doing high scans, the USB interface does limit speed a bit. My cpu is humming in at 20 percent, but USB usuage is maxed.
At $100, I would recommend this to anyone...might see if we can grab a couple of units for my department...
