I purchased an excellent condition Minoltina S for £39 recently which given the slide of the pound is less than $50. It's a fully manual camera, nice 40mm f1.8 lens. Selenium meter isn't to great. Decent viewfinder, not as good as Olympus RF that I've handled. RF patch lacks a bit of contrast but brightens with a very minute piece of black tape placed on viewfinder window. I replaced the light seals so now it's good to go, very compact and pretty fast even if f1.8 will be of limited real world use. Well worth the money.
Lens is pretty crazy wide open but plenty sharp -across the whole field by f4.
