I had one of these, and I got rid. I wasn't impressed with the quality (sound, not build). When you consider how much they've rammed into it for the price they sell it at, it does seem to good to be true. But... each to their own
I don't find there's an awful lot between the DN-X500 and DJM3000, but again, in my opinion, they're both audibly superior to the Fusion.
