I have the Driving Force GT, and I think its excellent, it has a shifter, paddles (or paddle buttons, but they are excellent too), 900 degrees rotation left and right, specifically designed for the game, and it fully utilizes the game too, so for those who say 'well it doesn't have a clutch or a gate shift' I say this game doesn't need it, and even if it did, you'd be hard pressed to find a 7-speed manual for the job, I'd imagine most would run out at 6, which leaves several super cars in an interesting spot.
I have a 23.5 inch 1080p monitor, and I raced for ages using a DS3, but this wheel makes it so much more fun. I would make sure that your desk has a lip to hold the wheel on though, I can show you pictures of my desk (I'm guessing you have a desk?), it has a fair bit of clearence, but you'll need that, and something to push the peddles against, I use my sub under my desk.
And I mean, where are you *chechs* Canada, oh yeah, I've been there, for you, how much will it cost *checks*... Bit hard to know without a post code, but the others never seemed worth it to me, anything over $200 for a 1-2 game peripheral seems ridiculous (no offence to any who bought that) this one will set you back anywhere between $80-180CAD, so go hunting for one from the 26th I'd say.
