check your data sheet for how much amperage you need.. a PIC usually needs
about 250 mA but i mean .5 A is probably sufficient in most cases. Just get
a a wall wart that's at about the voltage you need and buy a 5 V
voltage-regulator from radio shack.

the first one shown here will work fine. Although beware wall warts
are
typically not very accurate to the voltage they claim(i've found 10 V coming
out of a 5 V wall wart) so I'd grab a voltage regulator to make sure it's
accurate. 1 A should be fine for you. Anyway, that's my suggestion
