PSP on your TV
If you want to play Playstation Portable on your television set, you currently have three different solutions to choose from: The Blaze TV ( $59.90), the PSPonTV ($78.90) and the PSP2TV ($119.90).
All of them use kind of the same technique; some kind of camera, lens or small CCD converts the LCD display of the PSP into a composite video signal that you can plut into your TV. Lik Sang has published a small little comparison chart of the three different products.
