What is a good & Inexpensive Large format Flatbed Scanner? - what is the largest flatbed scanner size

I scanned a piece of art and you are looking to buy a scanner / way to work in large format. Of course, all this seems to me more than $ 1000 each. (too expensive) for us, someone knows where I can buy a cheap? Would the amount of at least 12 x 17 cm and not necessarily the film / negative system. Any help would be great.
