Next step up from my Rega P3

Buonarroti, My niece has a Rega p3 with the 300 arm and a Ortofon cartridge.
I think the P3 is a decent record player.
With your budget of 3000 bucks this would definitely get you a better phono stage and cartridge.
OR
Keep your phonostage and have it modified.
You have not heard all that your little P3 has to offer, not by a long shot.

Yes no doubt, Buonarroti, your budget is gone.
Next is your phono stage and choice of cartridge....
