Well, I have 4 of them: F, 2x F3, F55. F55 I got for free, it will be gone soon from my collection. I had before FG20, F801s, F50, FE, EM, FG.

F3 is the best for my taste. I have original F mainly to have body that will work all day without problem on winter when is -20C and below.

The only one that I would like to have also is F2.
