NI X1+Z1 vs. NI S2.

[Kimme]

Guitar player right here.

I recently borrowed with a friends Native Instruments S2 and really enjoyed playing around with it. I never

DJ'd before and I don't wanna do it on a serious level, I just want something to play around with and maybe

play on private partys or for friends. What I really enjoyed was the simplicity of the S2. I figured out most of 

the basic stuff within 15min. Only thing thats a little bummer for me is the size. So i found out about the X1 

and Z1 and to me it seems like ( correct me if i'm wrong please ) it's basically the same as the S2 with 

maybe less features ( like these "turntable-like scratch stuff ). I will mostly play with my macbook but 

with my iPad too. Would the X1/Z1 combination (although it's not really cheaper) be a good alternative

for someone like me? Or is there maybe even something else that i don't know about? Like I said, i just

want to do it for fun.
