the link to the interact site is down, so i'll add my two cents. i got one at fry's for the same price ages ago, and it is not like the playstation version in that it doesnt have a dpad or the buttons along the middle. mine has 4 buttons on the base, 2buttons on the wheel, and 2 buttons directly behind those on the rear.
regarding win2k support, i forget if it worked or not, but im pretty sure it should if you select a generic 2 axis (wheel?) with 4 or even 6 buttons.
well overall i'd say its worth the price. nothing fancy, not too flimsy, but i can say i had fun the first few days playing with it. its been under a pile collecting dust for the past months. i referred a friend and he said it wasnt stable enough, the pedals were kinda small for him (6foot guy) and returned it. oh, i believe it was 30-15 rebate or something.. again i forget if i received the rebate, i dont think i did.. (sorry for my lapses, i barely remember my freshman year of college =P)
i scanned that review and maybe the only thing i can add is the resistance is there, though not to the extent that it snaps back to center position.
so final words, if you're a racing junky, go ahead, its only 15bucks. if you're that cheap, you can return it (restocking fee?), or even resell it heh. if you're a pc junky, go ahead and get it, you'll have fun for a few days, then throw it with the rest of the junk you have. hope this helps, and remember mine is quite old, perhaps they've updated it.
