Whatever you get, if it's Japanese and hollow bodied, fill it with
as much modelling clay as it will hold. It will add (normally) 5-8 lbs in total...benefitting playback immensely.
I own both a
JVC QL-F6 and
QL-Y66F and they sound terrific (irregardless of money). The first cost me $100 and the second $400. Even after platter mats, new buoyant/feedback resistant feet (sounds like you'll need this), maple chopping block underneath and the clay itself...it adds less than $300 to the total of the deck itself.
Guess what? Unless I add the pricey
VPI SDS to my
VPI HW-19 Mk. III (a friend lent me his for a month)...the two above turntables sound
better than the VPI

So, a $750 limit can be met...giving you good sonics and ease of semi-auto playback in return

Good luck on your quest. John
