I'll throw in my 2 cents worth.....
I've got a FM2n, FE2 and a F5.
If you want MF the FM2n offers full manual and the battery only operates the meter. The FE2 offers auto shutter speed as well as the ablility to use exposure compensation +/- 2 stops but you need the battery to operate the shutter except on M250. Both offer flash sync up to 1/250. I really love both of these cameras.
If your looking for AF I only have experience with the F5. Great camera.
