sup guys im in need of a 4 channel mixer. Theres just too much in the 57sl for me to use and i love it. But 4 chanel mixer outweighs because of my needs. So i would like to trade it for a djm 800. they seem to be about the same price, only 100 dollar diference on the map on agiprodj. i can throw in something. But this is the only 4 channel mixer i will trade it for. Theres is nothing wrong with the 57sl and its in great condition. i know its going to be hard to do this because the djm800 is kinda new but it doesnt hurt to find out. If this post is out of line please delet it mods!!!!...
