but will be more fussy regarding matching a cartridge than the others (low mass arm for high compliance MM cartridges). Grados are a good match. Usually brings $250-$325 in the used market. This table would likely not have the speed problems your cheap Technics exhibits.

The Technics SL-1200 MkII has a large following and would probably be the better choice over the Denon.

If all these are in similar condition I'd probably lean towards the T60.

Not knowing your turntable budget, it is hard to make a recommendation.  

In general, direct drive turntables will introduce noise from the motor, and this is a bad thing.  

Think about it like this, in a direct drive turntable, the motor is attached directly to the spindle/platter and that's what the record rests on.  If the record gets any vibration from the motor, the needle will get the vibration too.  

A belt driven turntable isolates the vibration from the motor via the belt.  A better turntable will have a heavier platter to increase rotational momentum (keeping the record spinning at a more constant speed), but does not need very powerful motor.  

DJ turntables like the famous Technics SL-1200 series are made to get up to speed quickly so that a DJ can have a spot cued up, and then when needed get the record moving at the correct speed to match beats with the other music.  SL-1200's and other popular DJ turntables are not about extracting every last bit of sound from the disc, they are about making a great mix at a club to get butts moving.  

You might look at a used Linn Basik or Axis turntable, or there is also a company called ProJect that makes some inexpensive (relatively speaking) turntables.  

Don't forget that the cartridge is equally important in your whole equation.  A crappy cartridge on a great turntable sounds a lousy as a great cartridge on a crappy turntable.  Grado make some great cartridges on a budget.

Hope this was helpful.
