I agree with billyboy.
DEFINETLY, get the "industry standard" Technics 1200's new or used. The 1200's "new" will cost you about $419.00 each (if you get them at cost). You can probably
get them used for about $350.00 a pair, if you look hard enough.
Pick up a Vestax mixer 05-Pro, 07-Pro, or 06-Pro.
Some Shure M77's or the Ortofon that attach to the Technics headshells (not the ones that are "all in one", and look like "fingers").
You will need to practice, practice, practice, pratice...
It will take you a long time to learn how to do these newer scratches (flares, crabs, warps, etc.).
You will have to practice them until your forearm muscles ache (seriously).
Just remember that scratching is a learned muscle reflex, therefore once your muscles learn the "pattern" you will be straight for life (you might get a little rusty and not as quick as you'd like to be, but you'll not ever forget the "patterns" you reate and learn).
ALSO...
You will have to become ambidextrous, meaning you will have to be proficient with using your right hand as well as you use your left hand.
Example... your right hand is on the record and you left hand is on the fader. But you also have to be able to switch it up and have your left hand on the record and your right hand on the fader.
Have fun on your journey into the land of turntablism.
peace...

p.s. You also might want to find somebody in your city or town that has some turntables and a mixer so you can practice to see if this is really something you want to do.
