Nah, I always get cheap screen protectors off eBay most of the time, never really have issues with them. I normally get them for like $1 or less a piece and buy a few so if I screw up putting one on I have a few more chances, and normally if I want to spoil myself I'll change it after a year.
I normally take care of them, had a screen protector on my PSP since 2006 and it looks pristine.
