relevant but OT: automatic document scanning

I still have many many many large tomes and other printed material, including vintage docs, that needs to be committed to digital format. I'm always building something, and I gathered a hodge podge of materials in an attempt to fenagle my own document feeder (first thought I'd use a scanner or pair, later said screw that I'll just use a digital camera). Non destructive scanning isn't necessarily a whole lot more difficult in my estimation (using whatever curdled gray matter I have left), but who needs any more complexity then is necessary, so I opted for destructive scanning (where you rip the spine of the book apart and jam it in the mechanism). Then strolling through Target, I noticed the Epson Workforce 645 which allegedly can take a stack of 30 sheets and scan both sides. I'd prefer 30,000 sheets, but beggars can't always be choosers. So I bought it, but have yet to open it (my ethic states I shouldn't crack an item unless I'm somewhat positive I'll keep it. I _rarely_ return something I open. It bothers me to). So I would just like to ask if any of you all have delved into this. A piddly 30 sheet document feeder still requires you to "be there", although I suppose I could catch up on twiddling my thumbs at least while I reduce oh 300 books to bits and bytes.
