Amici 45* diagonal opinions

Does anyone know of any high quality 45* amici prism diagonals for birding use?

The Vernonscope 2" amici is one of the few options that I have found at $295.00.

Most of the few 45* amici prisms that I've located on the web are very inexpensive, and I suspect price equals quality - especially on prisms.

I'm using the TeleVue 60* Everbright now on a TV-85. I haven't tried TeleVue's 1.25" 45* amici or the Vernonscope 2" 45* amici.

Any suggestions or experiences with amici diagonals for birding would be appreciated.

Thanks,
Jay

Jay,

Our of curiosity, why do you feel you need one? A standard star diagonal gives an erect but reversed image. I've never found that a problem viewing birds or wildlife. I'm used to astronomical telescopes and find I often move my correct image birding scope the wrong way.
