Reply to What Audio Interace do I require? And DAW!

Hey fellow Techy's!

So I've basically been djing for a couple years with a Traktor s4, midi fighter, Traktor X1 and have a decent pair of Aiaiai headphones and KRK Rokit 5 monitor's running in sync with a Macbook Pro 15''. I intend to pick up a 49 key midi keyboard soon too.

I recently picked up the Maschine mkII with a purpose to produce music. I have no DAW as of now, but am looking to purchase the new Logic Pro X. Does this come with various vst's or do I need to buy them separately?
I may also purchase Komplete 9, is this a bang for its buck, and would it work in Logic Pro X? or do you suggest something else. I own massive and 3gb of a library that came with my Maschine mkII.

I believe an audio interface would work well with my emerging setup and can't really decide what to go with.

I've heard the akai eie pro has a lot of issues and hence started looking into Focusrite (who also claim to have latency issues because of the drivers) and RME (which I have no idea regarding).

Since you have a brief idea of what my set up is going to be like would you be able to suggest something decent. My price range extends to $300. Won't be able to buy one with a return policy because I'll be buying it abroad. So trying it out and then setting my mind on one wont be possible.

Thanks Alot, Anticipating an early response!
