I've never purchased from that particular vendor but I've ordered many times from vendors I've heard about through the slickdeals website. Both the deal and the person who posted the deal are rated by those who frequent the site. If any thing reported as a deal is incorrect, that deal receives a quick thumbs down. The posters are also good at rating the product once it's received.
From what I've read about DJ Hero, it's similar to Guitar Hero only the player uses a turntable rather than a guitar. It mainly has hip hop songs. There's also supposed to be a mode than will challenge the guitar (for those who have the guitar from GH) to the turntable. My nephew has been begging for this for Christmas.
