Help me to choose turntable below 1600$.

Thanks)

PLX-1000 is similar to iconic Technics 1200.

Rega RP-6. Not cheap junk like another poster suggested. I've owned those DD Technics players back in the 70's and I can tell you the RP-6 with a good cartridge will run all over them. Been there, done that.....

You can get a used or refurb Technics sl1200mk2 or it's variants and they are bullet proof.  Spend the rest of the money on a nice cart.  

plinth matters on performance and in regas it really sucks as well as especially platter. the only goodie is the arm that is barely adjustable oh well... highly doubt that rp6 is anywhere near sansui fr 4060 and quite far away from technics sp-10.
