There is a shortage of G27 steering wheels since GT5 came out.  I in fact had a G27 that i played a lot of Dirt 2 with, but I sold it during the huge run on G27's when GT5 came out.  I wasn't using it a lot and needed cash so i sold it for more than i paid for it thinking that when dirt 3 came out there would be plenty in stock.  Well Dirt 3 is a month away and still no G27's so i started to look for an alternative.  I set my sites on the Logitech Driving Force GT.  when doing the comparison on Logitechs site, the only real difference according to Logitech was the the GT did not have a clutch.   I never used a clutch when gaming so i decided to give it a try.
I picked up the Logitech driving force gt from buy.com for $129 with shipping.  I had used buy.com in the past and was not really impressed with them but they had the best price and with the seeming shortage of Logitech steering wheels I bit the bullet and ordered one.  I was happily surprised to find that the fulfillment and shipping were much faster and better, I would definitely use them again.

My GT arrived on Monday and I have been using it for shift 2 and dirt 2 and I have to say i am impressed for the money it is well worth it.  The one thing I was disappointed with was  the lack of support for it in Dirt 2.  It was easily remedied by editing the registry and telling the CPU that it is a Driving force Pro that is support by Dirt.

 
The first thing I noticed was how much quieter the GT is, the G27 is so loud that you cannot  talk on team-speak during a race.  The clacking and clicking was so loud that no one can hear a word.  The GT it is much quieter and it does not sacrifice  force feedback at all.  In fact the wheel feels almost exactly the same when driving.  Another thing I liked was the fact that it had less cords.  The GT has the shifter built into the wheel so you don't have to plug in another peripheral.  It also has the plugs in the back instead of underneath the wheel.  This makes it much more manageable.  It also has a gimmicky center button for the horn which I though was kinda fun.  Another thing is the arcade game support.  many games that are coming out now, have jumping and rockets to shoot and things.  With the G27 all those keys had to be mapped and the button placement was not very intuitive.  Since this wheel is designed to work with the PS3 it is ideal for arcade games like blur and such.
There are a few things that I did not like about the GT.  It is missing the leather of the G27 although this is not a huge deal, the leather does give you a better feel.  One thing that I really don't like about the GT is the paddle shifters.  The paddle shifters for the G27 are real paddle shifters unlike the ones on the GT are basically buttons.  They work and are not really hard to use but they just don't feel like paddle shifters.

In conclusion the driving force gt is a great steering wheel for the money.  If i had my choice I would definitely chose the gt over the G27.  I like it because it basically feels and reacts the same as the G27 but it is not as loud or as difficult to set up.  I give the GT 9/10 stars.  Better hurry and get yours before Dirt3 comes out.
