Looking for a 3rd party K mount 85 1.8 lens

There's a lot of small and cheap 85mm 1.8 3rd party lenses for sale, but I don't see any for my K mount Pentax. The sample pics look pretty good, w/ most of the lenses running $100 or less, even w/ AF. Does anyone know of a budget priced, K mount portrait lens?

I'm unsure if I can replace my Nikon w/ a little Pentax MX or KX, and don't want to tie up a lot of money in an 85 lens if it doesn't work out. Looked at a Pentax branded 85 1.8 at Monument Camera today, that $479 price on it stopped me dead in my tracks.

Closest is a Soligar 8t 1.8 in t mount, I think they fetch a fair price. I just don't recall many 85, there a are few 90s out there. You can check on the Pentax Forum lens data base.

Takumar 85mm f/1.9 + K-mount adapter though probably not cheap.

Pentax also made K-mount 100mm lenses.
