[WTB] 3x or 5x Prism

I've got two things: an astigmatism, and $200.

Prism optics have been the way to go, I have a few 1x's already and would like a 3x or 5x for a different setup. Would really like a PA Slx microprism 3/5 but open to others too. Lemme know what you've got that you're willing to let go for $200. Thank you!
