I was happy to recently find a used TL-120 and intend to take some great stuff with it.

But the backbone of my stereo shooting has been the TDC Colorist I & II. The winding spool typically needs to be repaired or reinforced, and the focus/controls usually need a good CLA. But it's worth it because they're effortless to use and have the most consistently sharp and contrasty lens of any Realist Era camera. You won't find anything better for the money.
