G25 Racing Wheel PC Wheel (Logitech)
This £200 wheel is the BOMB! Decided to spoil myself with this baby as I was getting a bit tired of my £20 one. This whell already makes me a better player at GRID: Race Driver. There are turns that you just couldn't do so well with a lesser wheel/ pad/ keyboard.
The way the thing reacts when you bash other cars. The gearstick is an awesome accessory too (although it feels a bit tacky compared to the super strong wheel and pedal).
So long as this thing lasts its 2 year warranty and beyond, it seems to be worth every penny so far.
