I bought the Dual Strike from CompUSA for ~$40 to help my crack habit (actually, its my Counter-Strike habit...but I've come to equate the two...

) Then a couple days later, Best Buy had their demo reduced for $14! Talked the salesman down to less than $10 since their demo didn't have box, instructions, install CD -- but I *knew* I did have that stuff at home... Burned the CD (hell, MS is GIVING the thing away,...right???!!!), repackaged the goods I purchased from CompUSA & returned back to them to get my $40 back.
Controller isn't bad...especially since I'm more joystick oriented (just put me on a spit and fry my a$$ if I'm expected to play with a keyboard/mouse...just ain't no good at it). Personally, I've been enjoying the controller. And it has enough buttons to map what I need to get the job done in the game...
