I am new to the home theater world so I appreciate any help I get from you guys!

A friend of mine (I think) wants to sell me a brand new set of home speakers new in the box. They are Millenium 2006p speakers 5.1 500 watts. He says they are worth 1700 bucks but only wants 100 dollars for them. My question is does anyone know about these speakers? Is he trying to pass on a bad deal that he may have gotten? He says they were given to him, but of course I am having my doubts as to the price issue, and I cant seem to find a website that gives a definitive answer, to the quality or cost of them.
