Rebuild suggestions

I have 3 thyssen elevators that are 25 years old and need to be replaced, most parts are obsolete for the ones we have, 1/3 of the elevators has a failed "tape reader" which the reading unit needs to be removed and the board fixed which will be a 2+ week repair. This has brought up the fact that the elevators are going to be replaced. Need recommendations on which brands to go with, Otis, Mitsubishi, ect.. thank you
