Im thinking..
£450 for the 2 x 1210's boxed , 2 x Blue Stanton I-track carts, 2 x Grey Drizzly records slipmatts + 2 x Black technics slipmatts
£300 for the DJM 500 ( ill throw in a good pair of 1/4 jacks if your amp takes them)
or £700 for the lot
everythings in good condition as i take good care of my music equipment and everything will be given a full clean and polish before sale :)
