After market power windows with altis switches costs 18k, while with local made swithces and used motors it costs 6 to 12k. The only problem which occur in ff and after market is the rubber channels in which the glass is moving, dueto manual assambly the xli channels are narrow, that decrease the speed of glass movement as well as there is always a danger of burning motor, or dechanalizing of glass. FF power windows change the channels as well, and if u argue with them they change the door panels to which left no hole.
