I'm a bedroom dj (meaning I do not play professional gigs), I spin trance <3
Although I haven't bought any vinyl since 2007, I've got 2 x Technics 1200s MK5s and two x Pioneer CDJ 100S (old, old, cheap base models).
What kind of info are you looking for?
Equipment and music (mostly mp3s these days) can be relatively expensive. Also, most people are digital these days and use controllers like Traktor and Ableton with their laptops.
