i would say 2 cd turntables and a mixer for you to start..
i used to use the denon's back when i used to fool around spinning...
you can get some used 3500's on ebay for about $250 each..
i used to use numark mixer
this looks pretty good for a beginner just to see if dj'ing is for you or not..

i will say that dj'ing is a lot harder than it looks..
anyone can cue up songs, but fading into songs without notice def takes some practice..
