i honestly wouldnt pay more than half for anything thats not fresh from a store. I may consider 60-70%!but its got to be so pristine i could eat my lunch off it. and be in box with all plastics and shit. outside of that i personally wouldnt consider it. i just sold an mpd, still in box with all the stuff in it, used three or five times tops for less than 30% what i bought it for
