you shouldnt HAVE to buy anything mate. just buy what ever you want to buy that you think sounds good, yeh to be honest i do find some of the tidy and nuk stuff quit banging but i dont usally buy it.
When i first started out djing i liked these labels alot.. Tidy two is alright, the last one i bought was 'DJ Vortex - incoming'.

Do you really get rotten fruit thrown at you?
