I was looking for a cheap steering wheel to play a driving game, cheapest I could find was this.
It doesn't get rave reviews, but it is a budget jobby and seems OK to me, works well with the game and for the money it's well built.
Could possibly break in the hands of a ham fisted teenager according to the reviews, but reading between the lines and trying it out you'd have to of had a lot of ham!!
Usually £40 - cheapest I could find
