Wow, the resale market on the G27 is ridiculous, they want more for it then what it used to sell for new, on principle that is hard to swallow.
Given the higher cost of the G29, in addition to the shifter that needs to be purchased, would you still go for the G29 or the Thrust master T300RS with the better Pedals and shifter?
It's easy to find feedback on the G27, not so much so with the Thrust master and how well it works with emulated Arcade games.
