Reply to Where to start?

Hey guys, first post on here and I am sure you guys get this a million times but I am just looking for some advice on my journey to becoming a DJ.

I have had a passion for music, mainly hip hop, since I got my first tape at 12 years old and am just now finally looking into doing more with my passion. What I want to do is pick up a entry level setup and just see how it goes as I don't want to fork out thousands and then discover it just isn't for me. I want to learn how to mix music and play around with scratching etc but since I last checked DJing has come a loooong way in the sense it aint just 2 turntables, a mixer and a box of records. You guys now have cdj's, serato/traktor, midi controllers(believe thats right) and a whole lot more which makes it quite intimidating and confusing...

I am looking at getting into vinyl over cdj's because the general idea I am getting is most prefer vinyl for scratching/mixing hip hop. I am just looking to do it as a hobby so nothing serious but I am getting caught up in the sense of if I buy my 2 turntables and a mixer just to wet my feet, am I basically going to have to 'stock' up on a whole lot of records in order to have a wide range of music to play with. I have a ton(and I mean a ton) of music on my PC which seems like a waste if I go the vinyl route...Also, this serato/traktor business is basically using your digital music library, on vinyl turntables, correct??

Can someone chime in and give me an idea of what I am getting into...? I am sorry if I sound like a fool but I have been non-stop researching this and there is just a ton of info on the web, my head is about to burst''
