If you are looking for a good quality screen protector, try www.boxwave.com
and then the Crystal screen protectors.
They are very tough but more importantly very clear. They do however have a glare problem. I find the Boxwave Crystal does not dull the screen as much as other screen protectors.
Plus, they are cut to match the BB 72XX!!
they are expensive at $10 per,but last forever.
BTW, I do not work for Boxwave just a happy user! I've been using Boxwave screen protectors on my Palm Tungsten E for the last 18 months.
