I hearded the vestax was good, they dont use acetate. so they wont die out after 100 plays or whatever. But there not for sale anymore.Since a long time, no one bought them. And if you own one now, you cant get the vinyl to cutt it into (i forget what kind of mat4erial it is but its very hard to get)
As for dubplates, check out this place in Uk, pretty cheap, and they'll ship anywhere.This is where Roni Size among others get theres done.
Ya dub plates don't last very long. I would say even after 20 plays the sound quality is greatly reduced. How do I know ? becuase I have pressed a few of them. I have used scratch free and they do as good a job as any in this city but they don't master well. Most places won't master a dub so its up to you to get the sound right.
