wink wink,
Sure, let us know what your PC specs are, especially the operating system (older versions of Windows don't always play well with USB).
You will want to look at something like one of
these. In the US you can find PCI USB cards for as cheap as $10-$12. As with everything though, you get what you pay for, so the absolute cheapest product may not be the best answer, but you shouldn't have to spend too much. The card I linked to was on Newegg for around $25US.
Have a look around your area, let us know what you find and we'll go from there.
