dude, if you have a psp 2000, sony makes a rather affordable, 15-20 dollar headset, specifically for your psp (for the skype feature). If you have a 1000, you can get a mic for it on EBay, but it varies on when they are available. There is a seller in Japan, that sells mics that are compatible with the 1000, and they only cost $13 with shipping, but they take about 2 weeks to arrive. I just checked on EBAY, there are none up now, but usually every couple days they relist them, so just keep checking.
