Hi. Does anyone have any recommendations for an A3 scanner? Looking on Amazon, there seems to be a massive leap in price from A4 to A3. You can pick up a fairly decent A4 Canon for about £49.99, but A3 seems to start at upwards of £200 for something similarly reasonable, and I was hoping for something more affordable. Any suggestions (including any other places to shop for scanners)? Cheers.
