Garage sales in Fresno are a whole different breed of risky, and cameras are the worst offender. The seller always has some story about how their uncle bought it new in 1985 and it sat in a closet, but the foam seals are mush and the shutter sounds like a coffee grinder. This is really just the same thing as a used car with 40,000 miles that somehow has a brand new steering wheel, or a house listing that says "cozy" when it means tiny. If a deal sounds too good, there is always a catch hiding somewhere. People selling stuff know exactly what they have, and the word "barely used" is usually code for "I gave up trying to fix it." Save your money and buy from someone who lets you run a roll of film through it first.
