I need a USB keyboard for my Mac. Since you can get PC keyboard pretty much anywhere for $10, I assumed that there would also be cheap Mac keyboards somewhere, somehow. I can't seem to find anything under $40-$50, though. What are the cheapest keyboards out there? Is there a particular store people order from? Or is my best bet to buy a PC keyboard and Sharpie the Mac keys onto it? Ghetto, I know, but I might just get frustrated enough to do it.
