Bought one of these beasts six months ago for £130, purely because I needed a A3 ADF scanner and buying a all-in-one was a LOT cheaper than a standalone A3 scanner never mind one with ADF.
£99.99 and a potential £30 cashback from epson make this an absolute steal. Just a shame I already have one already. Be aware though these are on the large side.
ADF = Automatic Document Feeder
