Some advice on the steering wheel please...

What is the deal with the costs of the after market wheels?


Due to my 'mass' I am going to need to be able to remove the wheel to get in and out. Can I get the hub from Pegasus and mount the OEM steering wheel to it? I notice that some of the circle track mail order places show wheels in the $2-30 range.


Can someone please give me a clue?
