I just split these posts out of the other thread so it can spawn a discussion of its own.
I recently bought one of these
http://www.obutto.com/ which is less cockpit styled but combined with a g27 makes one hell of a setup to play racing sims with as well as other gaming duties.
At the moment i team it with a moderately specced HTPC &/or PS3 connected to a wall mounted lcd, works brilliantly with GT5 in 3D
(you just need an understaning mrs to put up with it in the loungeroom)
