All the idler drive decks suggested are total rubbish and should be sold as cheaply as possible
Seriously, the collapse of the mid-priced HiFi market in the UK at any rate has seen the rise and rise of these venerable old decks which were all but given away in the 70's to be replaced by the better direct drives out there. I'm not saying this was wrong, but we didn't have the decent plinths and pickups back then to fully exploit what these decks could do.
A Lenco, 301/401/TD124 in a 1970's plinth will rumble, whine and feedback their way through your records, so despite the prices going through the roof for the bare-bones chassis, you'll have to spend a fortune on servicing and re-plinthing them, by which time you could have bought a modern deck - up to you..
My favourite oldie has to be the TD124. I saw a mint one again very recently and nearly wet meself, it looked so gorgeous - it's the one oldie (with the Sony TTS3000) I've never owned, although I've serviced a few in decades past. The owner is going to have a period plinth made with rounded corners (like the Schopper/Ortofon one). Amazing that, according to Gramophone magazine at the time, a TD125 cost more when launched than a 124 and 150 added together and was regarded as a better deck (I must admit mine runs totally quiet through the speakers with very low perceived surface noise and no (elastic band) pitch issues I can hear).
