The hobby your thinking of taking up is an expensive one! A lot more expensive than most computer hobbies. Vinyl costs lots of money, and it's the type of thing you'll always -need- more of.
My suggestion to you is to wait until your not inebriated before making your final 'investment' decision… even if you've been thinking about it for a while. That, and find the type/style of music your into, and avalibility on vinyl... find out just how much you'll really need to spend to get 'up to speed', because you'll probablly end up spending twice as much for the music as you will for the setup to play it.
As I'm not a professional DJ, I don't understand why 'braking' would be so important... unless you plan on relying on your turntables to do a 'spindown' at a certian speed. From what I've seen of my friend who -is- a professional, when your running, you don't stop the table... you let it spin while you change disks. That's what your slip-mat's are for, right?
You probablly don't -need- different needles. They might be nice to have, but a good set would be fine for getting started. You'll want a good slipmat before you'll want multiple needles which you swap out mid-session.
MOOBash didn't happen due to the fact the chi-town crew totally flaked on it. We were down, but they flaked majorly.
