Reply to Midi Fighter Classic vs Pro. Would it be worth it to save my money?

I'm a very amateur DJ that is just starting to get into it. For the past 6 months I've just been using the Vestax Spin with Djay, just to see if I would enjoy it. Turns out I'm in love with DJ'ing, so I'm very excited to get more into it. I'm going to be upgrading to nicer gear soon, so by the end of the year I'll probably be using an S4 with Traktor. I've also been looking at the Midi Fighter and it seems like it would be an AWESOME addition. But, what I'm wondering is, would it be worth it to save up my money for the Pro? Or would it be just fine with the Classic? Leave your responses! I'm happy to be a part of this community!
