Turntable Recommendations?

[Beechwoods]

I'm coming to the conclusion that it may be time to upgrade my Pro-Ject Debut turntable for something better. I've posted before about the earthing question, but the general level of turntable noise on the Debut is annoying.

If I were to replace it I'd be looking for something second-hand, possibly vintage. I have no idea on price so it would be useful to have a guide. I can't afford anything more than £150. If it can't be done in that budget I'll stick with what I've got.

I'd be happy to hear if anyone thought there some basic mods I could perform on the Debut to do something about the way it spoils the sound.

Thanks for any thoughts!
