Like anything….once you take one apart a few times it gets easy (easier??) If the motor intrigues you and you can get it cheap enough….buy it and then buy a parts motor to learn on. Take the parts motor apart and put it back together again several times until you are completely comfortable with what needs to be done. Then tackle the better one. If you are lucky you will end up with one good runner….or if you are REALLY lucky …..two good runners.
