Item of the day time!
Turns out I never had this sorted out and listed.
There are, as far I as know, 2 Singsstar press kits. one is PS2 only, one is PS2 + PS3. Both include asset discs, game discs, mircorphones, cables etc. I'm offering them both. Keep in mind they are heavy.
PS2 kit (wired microphones, 1 game disc) - 70$
PS2 + PS3 kit (wireless microphones, 2 game discs) - 110$
