what to buy?

I would genuinely like to know what type of things are impossible without one

What? Rather than start listing things, I'll just point out that it allows you to to do rapid cross-cuts without occupying both hands. Plus there's nobody in the world even using both hands that can cross-cut as accurately as a crossfader.

yeah after checking how much GC charges for shipping to that area of the world i would do as they say and just save up

i would do that, but i use my ipad to dj, i use djay and i actually djed in couple events in my uni. so now after knowing more about djing i see that the ipad is just stopping from exploring this world more that's why i wanna get a mixer. it might take a long time for me to save up for more professional setup yet IMO starting with something cheap yet provides more options that what i currently have might help me get money faster.
what you guys think?
and personally crossfader is really crucial to me, with all respect to your opinions <3!
