What Scanner? Do you have one you like?

Do you know of an easy good scanner to use? I was thinking about how messy my classroom seems and how I want to clean it up! I had an idea. I get so overwhelmed with all the papers I get and the filing. I am a terrible filer. I hate it and I also can't decide where to put it half of the time. I do much better when I can just have it digital save it. Then I can type in the name of the document anytime and find it. I think It will like it much better if I could just scan everything in and hardly have any filing cabinets or clutter. I am ready to digitize my classroom. Anyone else doing this? what do you use?
