Momo, Omp and nardi are all quality steering wheels but expensive, mountney m wheels are ok and a lot cheaper, you will need a boss kit to attach the steering wheel to your column, all the wheels mentioned fit to the same style boss which is the six bolt type, do not buy the cheap chinese copies on ebay as they are very poor quality see link
