A very old thread but the subject may still be pertinent. As a paraplegic I recently sought an answer to this very question. One alternative I have found is the Simraceway SRW-S1. It is a turn key setup and you can be a para and be up and running with this product right after installation. My only wish would be that they sold it with an optional mount, as it has accelerometers etc. so it is like a wii device (I think that might be a way to describe it; never owned one). I am just providing this answer as FYI for people who might be Googling this.
