angled finder

[shaaktiman]

I am looking for an angle finder that screws into my leica's viewfinder (not on top.) The one they sell is super $$$. Any 3rd party ones that anyone knows of?

I have one that I occasionally use on the 90mem. It is not really mandatory, but it is so nicely designed and made, I don't think I would ever sell it.

I'm not sure if it would be possible to fit a Zigview finder. Leica is certainly not on the list, as it is desgned primarily for SLR's, but maybe some adapter could be made.
Of course there is the Voigtländer angle finder but that is a stick-on one,which you don't want. Cameraquest can supply it.
