To be honest mate, the equipment isn't necessarily the most important part of it all, once you've learned the art of mixing itself the equipment you're using becomes pretty much irrelevant after a while.
However, I personally would recommend buying something of better quality, if you're seeing this as a long-term hobby, otherwise you'd only buy now and then have to replace again later on. If you want something to use in the meantime though, try getting second-hand equipment.
I learned on cheap decks and a basic 2-channel mixer and it did me fine for the first few years, because the two most important things to DJing are knowing your tunes and practising. When I traded them in for my current Technics/DJM600 setup, I bought both second hand and they all still work fine - the only things I bought new were my CD decks.
If you can, try using the equipment before buying, whether in the shop or by borrowing someone else's, that way you'll find out if you like them or not. The two industry standard mixers are generally the Pioneer DJM range and the Allen & Heath Xone range (I've never played a club that didn't have one or the other) and thankfully I had a friend with an A&H already which had already taught me how much I hate them, and it made my choice of mixer very easy. I find the A&H mixers horrible and soul-less, and as such I'll only ever buy Pioneer.
But as I say, you don't have to start with one, in fact, you might be better off buying a cheaper/second hand one to learn on first just to get yourself into it before spending the big money on a better one
So sorry to be inconclusive, but I hope this helps mate
