>>3379626Look for a Pentax P3n (or similar variant)
I got mine for $20 with the original manual, 50mm f2 lens, strap, and an auto flash from ebay back in 2015. The catch is that the camera is all plastic, and doesn't let you set the film speed manually. It reads the DX code and meters based off that. It has can do manual exposure, aperture priority, and program modes though.
Pic is my doggo taken with my P3n with a Super Takumar 50mm 1.4 on Ektar 100.
