Focal Price - Sony PSP Screen Protector - $0.01 USD + Free Shipping
I mentioned in another post that the 'Baby Octopus Comcorder Camera DV Tripod' looks like a good buy for 0.99 - another option you could pair it with! - http://www.focalprice.com/DT019B/Baby_Octopus_Comcorder_Camera_DV_Tripod_Black.html
The screen protector fits all PSP models. YOu could also cut it down to size for iphones etc.
