I have an Epson Perfection 610U which is very good.  USB interface is
fast and setup was a breeze.  Epson are also "good guys" when it comes
to releasing specs and/or sponsoring free software development.
Imaging quality is excellent.

I think I picked it up for about sixty quid about a year ago at the
Saturday markets on TCR.

The main smoke-and-mirrors used by scanner marketing bods is the
difference between optical resolution and the resolution the thing is
capable of outputting.  Optical resolution is _REAL_ resolution: how
many pixels per inch can the thing image.  They use software
interpolation to increase this figure but you don't get something for
nothing.  Consider opening a 72 dpi image in Gimp and blowing it up to
twice its size and you'll get some idea of what "interpolated
resolution" looks like.
