Can I ask about the whole SL1210 thing. I get the idea which is to buy a stock deck then upgrade it bit by bit as and when funds allow up to the point at which only the motor is left from the original.

My questions being - is the same motor used in any other (non-technics) TT?
If not, why? And why does someone not buy a supply of these motors and build a whole new deck from scratch starting with the motor? Apologies if I am missing something obvious.
