On the G27, I nearly bought one from here a few years ago when Ace had them on offer for around £170. Considering what's gone on at Logitech over the past few years rjk did well to get them down to £200. Still a good wheel but hard to recommend with newer tech priced so close.
I have the TX myself. Fab wheel, absolutely faultless so far but the pedals that come with it are a bit meh. No clutch and barely any brake progression, pretty much the same pedals that you got with the old F430 wheel. Thrustmaster have just released the T3PA pedals as a standalone set, which at the moment is only available from their site. Not sure if OcUK will stock these as I might get them further down the line?
