Zeiss Universal Or Leitz Othoplan...Which One Would You Buy?

I have an opportunity of buying either a Zeiss Universal or a Leitz
Othoplan.

Which one would you buy and why?

I have been searching for information for both scopes and have found
very little.

Any suggestions as to where one can find more information on these
scopes?

Also...how easy and affordable are other lighting options (phase, DIC,
fluorescence, polarized light) to find for these scopes considering
that they are older scopes?

Thanks
