Official Sony Dualshock3 Controllers. Available in Black, Metallic Blue and Satin Silver.
These are selling at over £40 at most places. Checked against Amazon, same price on the black one, all others are atleast £5 cheaper.
Also heard something about 3rd party controllers becoming inactive due to firmware updates so this could be handy for those looking for extra controller(s)..
The DualShock 3 wireless controller for the PlayStation 3 system provides the most intuitive game play experience with pressure sensitive buttons and the inclusion of the highly sensitive Sixaxis motion sensing technology. Each hit, crash and explosion is more realistic when the user feels the rumble right in the palm of their hand. It can even detect natural movements for real-time and high precision interactive play, acting as a natural extension of the user's body. The DualShock 3 wireless controller utilises Bluetooth technology for wireless gameplay and the controller's USB cable to seamlessly and automatically charge the controller through the hardware.
