djcontrol instinct vs mp3 e2

hey guys,

i know this question was discussed here a long(er) time ago. 

i am about to buy a hercules mix and would need to clarify a few things. 

as far as i understand, the main difference between the two models is that the instinct has a dedicated 3,5cm jack output as well as rca output. 
for the mp3 e2 i wasnt able to find out, what output it has.. perhaps none ? and it just sends the signal back to the pc, from where it has to be output ? ive never seen this before but i guess it is possible. 

so one does have a sound card and the other one doesnt.

also, the mp3 e2 jog wheels dont have the scratching capabilities.

is this correct ? 

would need a response asap if possible 🙂
