Gadgeteer.com has the review for Bosity enhancement Screen Protector. This enhancement PDA screen protector is very inexpensive and long-lasting. It is washable, reusable and anti-glare. The screen protector has a gentle adhesive back. It is practically available for every Sony Clie, Palm, iPAQ, Toshiba, Dell Axim, Pocket Loox, Handspring handhelds as well as some Smart Phone.
I've used CompanionLink screen protectors from http://www.freescreenprotectors.com/ for years on a number of devices. Use the discount code FREESP and all you pay is shipping. They are anti-glare yet nicely transparent. I've never had a problem with them, nor seen a reason to spend more money for the same protection.
