The Marantz 6100 has that standard Marantz design from the 70s. Some love it. Some hate it. It’s basically an entry level turntable but it’s still pretty good. It features a belt drive, hydraulically damped cueing, and anti-skating adjustment. It will run at both 33 and 45 speeds and has auto return and auto shutoff. The 6100 was produced around 1976 and was most likely made by CEC for Marantz.
The Marantz 6100 is fairly plentiful and can be found for very reasonable prices. It will make for a good entry level table for someone just starting out in vinyl. A belt drive system isn’t necessarily the best but it can suffice. Just keep in mind that nearly all older belt drive turntables will need their belts replaced. Fortunately belts for the Marantz are obtainable.
I’ve seen the 6100 sell for $300-$600 in restored condition. Usually though they will sell for around $250 in average original condition. At that price level they will most likely need a minimum of basic servicing.
