  Also, quite often I'll prefer to deal with 3 if-else than with a factory. One of gurus I know has a rule of thumb: Make generic solution when you do it 4th time. Only then you have enough info collected from special cases that the generalization you design has chance to be future-proof.
  
  If you do generalizations too soon, you are something Joel Spolsky calls Architecture Astronauts, who use so high abstractions that they run out of oxygen
