if your laser printer loads paper from below (the tray is below), then the cardstock will curl. If you can load your paper from outside, so it feeds straight, then the cardstock will most likely stay straight. I have a Phaser 8560 so my printer prints it fine. don't bother to try to have Kinkos print it, because they will refuse to print on metallic cardstock. You may find a local mom and pop printer, who can give u a good deal. you can bring your own paper that you already bought. just a thought if it gets too frustrating.
