Kickboxing for a 2nd martial art

[mma geek]

I'v done Karate for about 3 years and I want to do like 4 other Martial arts but I can't pay for all lessons at once. I'm thinking when I get my Black belt in Karate I want to do kickboxing. But I don't really know if I want to do Kickboxing or Judo first so what do you guys think I should do?
