All scanners have their ups and downs. The real trick is to pick one that will last. HP however, has not been known to last long without breaking down. I have seen/got stuck using HP devices MANY times before. Scanners, CD-Writers, printers, others.For the past four or five years now, they have been doing nothing but causing problems!! Don't think so?? Check the Technical Q&A Hardware section. Oh look, there's an HP printer already in action!!! I have also used scanners from Genius, Microtek, Cannon and Logitech. Any one of those should do fairly well for you. Cannon and Logitech scanners usually have a higher price tag but it's usually with GOOD reason. I setup a Genius USB scanner for my cousin. He couldn't be happier with it!! Also, the Genius scanner usually has a smaller price tag. I would also suggest you aim for one that has the photo negative scanner. Genius and Microtek, I pretty sure, both have that option. Basically it will just give more scanning options to you.
Have Fun!!!
