Mine are my Nikon F5's. They are built like a tank, and are about as heavy. However when the strap on one of them let go and it landed on an ice covered, paved road there was no damage.
The metering is unbelievable. I have tried to fool it, but it always beats me. I no longer even bother to bracket, and that includes chromes.
I have to admit however that I do miss my motor driven Nikon F's that I had as a teenager. They had a great feel about them and if I can find a couple in good shape my bank account will take a hit.
