Reply to s4 vs dx (PRICE DROP)

first time posting here..

currently use a numark ns7fx..

so i am used to ITCH, never used traktor before

i (impulsively) bought the s4 recently with 15% off

i see that the xone dx now goes for $469 !?!? it went for 1200 at the time i bought the ns7fx..

is it a bad idea to swap the s4 for the dx? or is it worth learning how to use the s4?

considering this because i am more used to itch and itch 2.0 seems pretty solid

ultimately, i want to do 4 deck mixing (with cdjs and no dvs, which is my next step)

i play almost exclusively house/electro/trance
