Can anyone recommend any old, cheap 35mm RF's - ie less that 100 ($150). I need one to take places I wouldn't want to take an expensive camera, and I want it small and inconspicuous with just a 50mm lens. I had a Yashica Electro GT to take to Glastonbury this year, but it suddenly developed light leaks, so needs replacing. Before I buy another Electro, is there anything else I should consider?
