When I said 'decent collection' I originally meant quality, not quantity John....in reference to Marks comment that it's the tunes that count moreso than the person spinnin' them.
However, in regards to quantity carried in DJ boxes, I would not feel comfortable arriving at an allniter with a mere 100 records....unless I was confident that the other DJs playing didn't have any of the tunes I was carrying.
Certain records are bankers / floorpackers, others are ones I want to try out and others perfect for changing the tempo or genre of music being played (and yes, before some one comments, some are no doubt crap.... )
To have the choice is paramount, especially if playing to a crowd you are not used to, and I don't think 100 records would give you enough choice over a period of 9 hours or so.
I've seen Dave Evison DJ with a carrier bag before now....but that's cuz we make him wear it over his head so he doesn't scare the crowd
