Reply to trouble choosing software

So since i play at a lounge every friday and saturday i was believeing about changing from ableton to serato. I go down to guitar center to check out a ddj-sx and i see a twitch for 100 dollars used. I believe what the hell its only a hundred and it will give me a feel for serato. So i download itch and i absolutely hate it. The software cant beatgrid for shit, the keylock sounds absolutely terrible and i hate the effects.

I like the feel of the ddj-sx but if serato dj is going to be like itch i would rather just save my money for 2 months and get some cdj2000s and a good mixer.

Ive never bought top end or pro gear before so im kind of lost or feeling in the dark here. If any serato dj users or cdj2000 owners chime in i would really appreciate it.
