Micro Seiki HS-80 flywheel (reproduction)

This is a reproduction of the Micro Seiki HS-80 flywheel, used with a variety of the larger Micro Seiki tables such as the RX-15-- series, RX-3000, RX-5000, and SX-8000. 
String drive. Seven pound Stainless steel platter, overall weight is over 20 pounds.
I am assuming that anyone who is looking for one of these knows exactly what it is, and how, and why it works. 
Price reflects the fact that this is an accurate, fully functional reproduction and not an original, though I doubt there are any functional differences. This was machined by Mirko Djordjevic of Classic Turntables and the machining is top notch. I don't think he made many of these, and there was a long wait to get one, but the workmanship is extraordinary. I have owned this for about 9 years now, and the original price was around $1,500 if I recall correctly.
I have a short video showing the concentricity and spin, but don't seem to be able to add it here. Interested parties might contact me for that. It's essentially perfect, though that's a loaded word.
