having owned and been a loyal fan of sony playstation through the years , i find though behind the competition in putting their products out to market before the best they have to offer , they at least when they do...they get it right. cheaper to buy as console bundle with 320gb as i did for son but if considering getting involved with the move range then this is the next cheapest buy, than buying seperately, you can get by on this alone and dont need two controllers to have two player or more action. as a starter ...(the names in the title) you get all you need . dont forget you can also video chat to other ps3 users who have the camera microphone. hours of fun for all the family , arguments all round as other opinions for other consoles systems . all i know is , i was going to get the wii for my girls for the interaction game play and just in time , sony release the move , got them set up on my ps3 with 3 move, 2 navigation , quad charger, attachable sport accessories and 2 guns, 3 games and though financially it all adds up , i believe a good investment , and saves having to cross systems to the competition.
