@jasonbourne71 ...It surprised me at the time....not the best MC, but it outdid the Stanton 681EE MM cart I had at the time...
What really caught further imagination about the 10 was it could be run on 12vdc; there was a jack on the back of it (if memory isn't total trash....I even have my moments of doubt, just to speak potential truth to a vague concern of mine...and perhaps to verify that of others... ;)...)
I could see an SL in a motorhome, happily playing en route...you could (and I did) pick it up and turn it over, upside down while playing....and not miss a note.
Astounding....If you rotated it horizontally, it would 'wow'...but not skip....
The cart is near unobtainium these days...even in Japan....*sigh*
