I've never shot film before and I have very limited experience shooting with fully manual exposure.

I saw a post for a Pentax K1000 with a very extensive set of glass (plus some extras I don't really care about) for only 200 bucks

Should I go for it?
I'm not bothered by manual focusing at all (I usually manually focus on shitty dslrs anyway because of the slow hunting around AF) but I fear I'll burn through rolls of film without a single decent shot trying to figure out manual exposure
