USB port pc card

or to be exact, a PC Card with two USB ports, now as some of y'all know my laptops USB ports broke when i sent it to be fixed last time.
now i cant afford to pay for it to be fixed as it is out of warrenty and it cant be done by a shop down the road because it needs to be sent away. Now i have found a PC card that will go into the slot on the side of the laptop which would give me two ports, however details of how good they are and just what can be used with them are sketchy.
So does anyone have any experiance or knowledge with these devices??
