greetings fellow psp gurus.. i would want to go get my very first psp tomorrow.. preferably low yat plaza la.. so guys any recommendation on which place offers the best deal??

greetings guys.. i would wanna know.. how do i get to use the skype in my psp... i know we require a specific headset with mic for it.. but how do i go about getting it? does third party makers sell it or only sony does it? and how much does it costs? im an avid skype user and it would be better if i get to keep in contact thru my psp too...
