Picking out a Wheel for GT5. Have some cash, need suggestions!

Ok, so my girlfriend wanted to get me a racing wheel for my birthday, but she couldn't afford the G27, but she gave me something like $130 towards a wheel. I could probably throw more of my own cash towards a G27, but to be honest I have to buy christmas presents. What do you guys think? Is the Driving force pro any good? What about that with the PS eye for head tracking? Are there any other wheels comparable that have shifters? Which is my favorite feature of the G27. Im so looking forward to this game, and without a wheel I feel like I'd be missing out.
