Shawn,

If you don't mind something a bit ugly compared to the FE, but same basic camera, there is the EL2. Has a true mirror lockup. Unfortunately, it's not compatible with the MD-12 and does take the PX28 battery that goes into the mirror box. Otherwise, it's essentially the same. Another option, if you don't mind doing the "Nikon Shuffle" each time you change the lens, would be to go with an EL or an ELw. They're pre-AI, so your Nikkors will need to have their prongs installed. Those cameras go for cheap.
