I'm pretty sure it was the self-timer that was keeping the shutter from firing. I took it Columbus Camera Exchange (which, if you are in the Columbus, OH area you should definitely check out) the other day. I was going to see if they'd buy it back for parts, but before I could get the entire story out of my mouth the owner shoved a Minolta Hi-Matic E in my hand and said "Here, take this." And then he wouldn't accept payment! So in exchange for a broken Electro 35 that I had no hopes of repairing, I got a fully function Hi-Matic. I love that place. Does anyone have both cameras that they can give me a comparison? Maybe let me know what I'm missing out on not having an Electro?
PS - I was also able to have my money refunded by the eBay seller. They didn't even want the camera back...
