I've had mine for about 6 months, and its been a constant struggle to get full use out of it in games. I've found LFS is by far the best, followed by NFS Shift on PS3. If you come across any games that it works well with, please post feedback!
Dude, reason you cant find g25 is because Logitech have released G27. Its pretty much the same but a few more buttons and shift LED's on the steering wheel.
