Largest Consumer Flatbed Scanner Can You Recommend An A3 Size Flatbed Scanner?

Can you recommend an A3 size flatbed scanner? - largest consumer flatbed scanner

I need an A3-format (11x17), a flatbed scanner for large magazines such as Life Magazine. The only thing I see in the consumer price is the Mustek ScanExpress A3 ($ 170) but has a resolution of 1200x1200. Everyone seems to press the 1000th Do you know of a different size A3 scanner for under $ 300 or less?

Even if you know what the practical difference between a 1-to-1 and 1 to 2 ratio dpi (1200x2400, or 1200x1200 disadvantages)?

Thank you!
