I got a Canon N670U last year for about £60 I think it was. Came with all software necessary for all my uses. Have used it to scan many hundreds of old photos for putting on CDs. It's a great bit of kit and sooooo easy to use.
I expect the model has been superseded by now and if so have a look for the latest equivalent. I suppose scanners are all fairly similar within any price range, although someone will probably know different, but the important thing is to make sure the software is what you need.
