From personal experience:
I have bought one of the those ebay steering wheels and it is junk. It bends a lot and sometimes its scary...
I then later found an almost new and genuine MOMO wheel on a forum for about 80 dollars and never had issues since then
I was fortunate enough to sell that ebay wheel and I warned the buyer so I could have clear conciseness haha
moral of the story:
spend a bit more money and time searching forums and buy a wheel that was tested and R&D'd (momo, nardi, personal, etc.)
you don't want the wheel to snap off mid drive, nah mean?!
