This is the model I own and use for my scans. It is a mighty piece of kit and at that price is a steal if the glass hasn't been scratched by some turkey feeding stapled pages through the thing.
The only issue with this model is if glass gets under the optics. I have had that problem with mine and couldn't get it serviced in New Zealand so I learnt how to dismantle it to clean the optics myself. You need to be careful as it uses mercury lamps instead of CCD given it is a 2008 vintage scanner.
If mine died I'd likely eBay another one in preference to any other unit out there.
