What is the ideal screen?

Ah, so you basically want to know what the cheapest, best looking, smallest screen is? :p

It all depends on the console, and the portable.
Actually try the ps2 screen it has the same circuitry as a psone screen and it is cheaper ($50.00)
Thanks. That's what I thought. I'm still deciding either to use a 7'' PS2 screen or the 5'' PSOne. I guess the smaller one to fit the case better.
