It's a bit pricey, but I used £350 of some money I inherited a few years ago on a Rega Planar 3 (aka the 'P3') - the best deck for under £500 at the time, and the one I used to master up the recordings for the compilations I used to release on Trybute / Reggae Retro..
However, it is an 'audiophile's turntable' & NOT a DJ deck, and I don't think it would not appreciate being hoiked around ! Plus to alter playing speeds you need to move the drive belt to differing positions, not particularly practicle if your mixing !
