Had a nice setup going with: 2x Technic 1200's, 1x DJM 400, 1x KP3, 1x Trigger Finger, 1x Axiom 25, 1x Laptop running ableton. Strictly bedroom setup, not for gigging.
Was spinning alot of Dubstep/Breakbeat. Had to chunk alot of stuff though awhile back while inbetween jobs. But damn I miss mixing on the decks.
Now saving up for 2x MK5's and a Rane TTM57. That's really all you need, along with a laptop. Easier than carrying crates of vinyl around, instant access to new releases on beatport and digital-tunes.net which is alot easier than paying 10$+ for a vinyl that's comming all the way from London or something. And you still have the ability to spin a old-sckool night with Vinyl only. Oh, and a EFX 1000, those things are so much fun to mess with.
Now I do my mixing in Ableton Live, remixing is so easy and fun if all you have is a laptop and alot of free time hehe.
