A difficult LP reproduction question

I have a nice high end system and wish to add a second turntable (for fun!). The choices are likely Thorens TD124MK ll or Lenco L75. Both these are old technology and will spin 78 RPM and use idler drive.

Desire is to experiment with moving magnet cartridge, inexpensive phono stages and 78 RPM records to name but a few.

Here are but a few of the economy priced phono stages that I've been researching for the past three weeks. (Hope that explains my lack of posting lately).
