Could you kindly share the deal link on eBay? Given that I have been a Mac user for the better part of my adult, it sounds like what you've found on eBay could be ideal for my needs especially if it is delivered with the associated PC hardware (that is dedicated for the sim software).
It was a one of deal from a private guy that had bought a dedicated PC and all the software and 13 add on,s I paid 500 quid for the whole lot, ti looked to me like it was a guy that had went to town and ordered the works then for whatever reason decided to unload it.
