Summary: I LOVE this scanner. It's tiny, lightweight, and can be carried in a backpack if need be. It's incredibly quiet for a scanner and has a bunch of fancy modes that I honestly never use, but hey, extra features are always nice.
Summary: This is for the budget-conscious (like me) and does exactly what I need it to do, which is to scan the occasional document. If you're looking for something fancier, I suggest spending a little more $$ on a more elaborate scanner.
Pros: Small footprint, lightweight, works as advertized.
Summary: For lots of photos, use a feeder ;) Remember to unlock the stupid scanner at the bottom....
Pros: I've been using this for scanning a few photos but mostly for scanning all the sheet music I've accumulated over the years. It works very well with Linux, since the SANE project supports this scanner. Naturally, the buttons won't work by default but that's fine as I use keyboard shortcuts anyway....
Summary: Cheapest scanner I could fine and it's pretty darn good. If you just want to scan bills and such for personal records digitized, then this is your go-to scanner.
Pros: Auto-scan does detect between images and documents reliably in the few times I've used it. Scans are crystal clear and sharp. No AC power brick - powered by USB.
Cons: Has a couple of attachments near both ends of the USB cable. I do not know whether these are filters or power capacitors or whatever else they could be, but I doubt it'll work with any other USB cable. - Untested so not docking any eggs for that.
