Forogt to metion - the TDC cameras have a habbit of breaking their take up spools (or maybe it's jsut someting we saw here in Australia??) but most of the ones I've seen have been repaired in some way (not an easy repair).

The local 3D club here would recommend a Stereo Realist or a Kodak.

I also forgot to mention the Fed Boy - the Russian 3D camera form the 80's. I have one, and mine works great - sharp photos, great AUTO exposure...and really easy to use...

You probably won't miss having a rangefinder, as you tend to work at f8 or smaller to get the best 3D results...things look a bit funny ot of focus in 3D :-)
