Bought this one off of Ebay:

http://cgi.ebay.com/3-Screen-Protect...QQcmdZViewItem

Nice, good quality, slight squeeshy feeling when using it from the thin silicon layer (I guess). It's a matter of preference, but you never know and its alot cheaper to replace a scratched screen protector than a scratched touch LCD. Never used one on my Treo 650 but I like the protector on the N800. $8.00 is not much to have a little insurance from the weirdness that life throws at you from time to time. Heck your Canadian dollar is kill us yanks here.
