I love the F's with straight prism finder. I have the older style, plus the later with plastic wind lever tip; both are fine, but I probably slightly prefer the older metal lever. I've never really liked the Photomic heads; in addition to other issues mentioned, the Photomic makes the aperture adjustment and lens changing fussier. The straight prism camera is a lean, all business, machine.
F's and many of the lenses are bargains now. In general I'm not as thrilled with the lenses as the bodies, but there are some that are exceptional and others that are incredible performers for their price.
