I've always been passionate about DJing and music production. I've finally got money to spend and get into the next level.
Which is the best setup/which setup gives me more options?

1) kontrol s2 and mashine
2) kontrol s4 and maschine mikro
3) kontrol s2, maschine mikro and kontrol f1

I don't have space/mobility problems.

Thank you very very much for the help.
