I'd assume the joytech would be the best screen since it plugs into the digital port, however it's PAL only.
Intec apparently is better than Interact, but even then the quality of the screen is in question.
I've seen several other brands, many are no names. I know there is a hip gear controller and screen in one, but I have no idea about the quality, and red hot games(spin off of interact) has a 'digital screen' but I don't know if it's actually digital or if it's just the name.
Thanks for any opinions.
