PSP Screen Protectors

[Tricky]

Just got myself one of these things and having looked at my very nice screen wondered - Has anyone with a PSP used these stick on screen protectors?

Are they worth it?
What model (screen protector) have you got?
Can they be removed (without marks etc)?
Would you buy them again?

I dont have a PSP, but use the same type of stick on protector for my PDA.

I think they are well worth it, can be removed without marks, and yes, I buy them again and again:)
