There are still quite a few turntables out there that have 33-1/3-45-78
RPM capability.  Probably the best is a used DUAL turntable.  These
were imported by United Audio and you can find a model 1209, 1219, or
1229 for somewhere in the $50 range (used).

Don't forget that for playing 78 RPM records you will need a spherical
stylus, not the elliptical type normally used for 33-1/3 LP's.  The old
78 RPM groove was cut wide and the modern elliptical will not make
contact with both the outer groove walls.  Stanton, ADC, Shure and some
others still have spherical styli for use in their cartridges.

If you have an equalizer in your system, you can get some pretty fair
reproduction from the old 78's.  The RIAA equalization curve did not
come into play until the first LP's.

I hope this helps.
