If you're using MM get a Slee. If you're planning to go MC, then you're struggling a bit, the Trichord at £250 is pretty good, but a little dull when I've heard, mind I was comparing it to a stage that retails at £600.....

The phono Tube-box might come in on budget, or the new Cambridge at £40 MM or £60 MM/MC has attracted a lot of attention. That might be a cheap way of seeing whether a dedicated phono stage is for you.
