you all are stupid!!! the core system has one controller and the unit (no hard drive, so you can't backplay or save games) and costs 299.99 and the pro system has a wireless controller, hard drive and a bunch of other things and its 399.99 and the hard drive alone costs 100 so it pays for itself just by that. and any microsoft retailer has to sell the units for that price because the prices are controlled by microsoft, just like the iPod is by apple. and the dealers for the 360 are: Best Buy, Curcuit City, Wal-Mart, Target, EB Games, maybe K-Mart and maybe a couple other places.
