It may be that if the electronics fail it cannot always be fixed. Nikon's supplies of spare parts dried up years ago (in UK) What they have resorted to here is canabilising other cameras to get them working again. FE2's are selling here for less than FM2's at the moment but There are a lot of FE2's that were bought as 'jewelery' and not used very much so you may still be able to pick up a decent one which has a long life ahead. A clean cosmetic outside is usually a good sign.
