Since you're in England I am not sure how feasible shipping costs would be, but a refurbished Epson 3200 is $299 with free shipping in the US and the 2450 model is $199 with free ground shipping in the US at

These are in the clearance center.

I have the 2450 as I won't print over 13x19 here at home (Canon S9000) and any larger I can get either a Nikon 8000 (soon to be 9000), Imacon, or even Drum Scan in my local area.
