I have a Hero, too. I just purchased Bodyguardz from NLU. I only bought the screen protector, not the entire phone kit. It was fairly easy to apply and it does slightly alter the sensitivity of the screen, but less than I thought it would. I can tell that it is on, but very small type on the browser is still quite clear. I heartily recommend this product!
I just got the HTC Hero and love it, but I want to get a good screen protector for it. I know some out there are super heavy duty but can feel tacky when touching them.
Anyone know a good screen protector that still feels good when using a touchscreen?
