how long's a piece of string?
I was beatmatching in 4 weeks. i'm still learning now.
I been djing 10 years.(i got them when i was 13)
i started with shitty soundlab deck's then when i couldnt mix any better on them. i saved and bought some 1210's. i still have the 1210's but i now have cdj1000's as well.
try and borrow or have a go on someones decks if you like it buy some cheap turntables(you can pick technics up now for£200), buy a bundle pack of vinyl off ebay(£50) and get practising. if you still like it. save up and buy some cd decks(pioneer Imo) because to be honest the new music isnt really being released much on vinyl.
hope that helps
