Do you have a budget in mind? That would help out a lot.
$12 - $15?
Thousand or hundred? There are options at both points.
How about just $15?
Mine:
1963 Bogen-Presto B51 (rebadged Lenco B51) classroom deck, before:
After:
$15 deck + $75 stone stock, + elbow grease and conversion to heavy platter (platter and bearing from donor). I also added a second Lenco platter to the deck for mass and added "flywheel" rotational speed stability:
Because it was so cheap (not cheaply made, just bargain cheap), I added a nice modern arm, by Jelco. This is a 12" arm; better tracking via better geometry.
Minus the arm, and cartridge, I have less that $100 in the deck.
