Advice on a turntable for a clean midlevel system

Any opinions on a turntable to fit my system; a work in progress? My consideration:
I have 2 in college, so i need to be cost effective. Thus, I am not in the $10,000 plus spectrum.
My Likes: a system that has lots of detail with sweetness in the midrange (the better to hear Coltrane's tenor and Madeleene Peyroux's vocals) , some sound-stage, I like everything from folk, jazz, classical and rock.
Current system: Panasonic techniques turntable from 1975 with Grado Gold cartride (this I want to give to one of my sons), California Audio Lab DX 1 NAD Integrated amp- plan is to upgrade to a Creek (5350) or Bryston, Tetra M1200 speakers- they fit my listening space well.
