Help me find value for Technics SP-10 Direct Drive Turntable


I have a Technics SP-10 Direct Drive Turntable that I would like to list for sale on Audiogon. However, Audiogon Bluebook cannot give me a current value to set as sales price (according to Audiogon Support, they do not have a record of recent sales).
Audiogon lists values for SP-10 MKII and MKIII, but these are not my model. Mine is the original SP-10, which is what is listed on the Serial Plate (no MK, I, or even M is shown).
This unit is from the estate of a relative who purchased it in 1975. It is in the original shipping carton, has never been assembled or used. Serial number is 60123. 
The unit does not include a tone arm, base or dust cover.
Thanks for any help you can give me. I am skeptical about using the MKII value as an approximation for this unit.

Wos and very interesting tonykay. I did list in on C*****st but Chicago area only and got an immediate call. Did you list is nationally?
No, just locally. I don’t want to be bothered with shipping or waiting for a check to clear. I prefer local cash and carry transactions.

I just re-read your post and realize it doesn't include an arm, base or dustcover. Obviously, you'll have to take that into consideration when pricing it.
The SP-10 is the cheapest in Technics SP series, for price sratistics check ebay for sold listings.

Personally i would avoid SP-10, look for SP-20 which is much better and closer to SP-10 mk2, but still cheaper than mk2. The SP-20 is very rare, it looks exactly like sp-10 mk2, but in a nice black finish (33/45 switch is different, no 78, and no external power supply). I have both SP-10 mk2 and SP-20 (which i like very much).

Pricing sp-10 over $300 is nonsense. While the sp-10 mk2 in perfect condition should be arround $900 and SP-20 somewere in between.
