DJ turntables like Technics have selectable speeds but are also insanely expensive. Lots of modern belt-driven players marketed towards audiophile hipsters don't even spin at 45 RPM (which is fine because the 7" records being pressed now mostly are often 33RPM anyways)

You need a special stylus and perhaps to adjust the tracking force.

The classic DJ turntable was the Technics SL-1200. It plays 45 and 33.3.

The Pioneer PLX-1000 is a near-copy of the old Technics, it also plays 45 and 33.3 rpm

Maybe the classics don't, but the SL-1200 variants here play 78: https://us.technics.com/collections/turntables

Wow, I admittedly had not been keeping up but had no idea they still made them, that's cool.
