best-groove, I beg to differ with your claim that the SP10 Mk2 does not rely upon a now discontinued chip. It does, in fact. Up until a year or two ago, that chip was unobtainable. (I think the part number is MN6042, but right or wrong as to part number, there IS a critical chip.) Many users of the Mk2 and the Mk3 purchase the one or two of the SL1200 variants that also use that particular chip, just to have a spare. However, in the last two years, JP Jones succeeded in producing a PCB that does the job of the MN6042 with even more resulting speed accuracy. And the PCB is not physically larger than the original chip. He sells it for a very reasonable price at Fidelis Analog. He'll also install it for extra cost.
As to the Pioneer Exclusive turntables, these are the P10 (not "PL10") and P3. The P3 is the ne plus ultra of vintage Japanese DD. The Pioneer PL70II is also very highly regarded and may or may not be competitive with the Exclusive P10. (See write-ups on Vintage Knob.) But the P3 is in another league, and another price range.
I agree with Raul; coreless motors are the way to go.
