I bought two galaxy tab screen protector from TJ Max for 4.99/each. Installed it tonight by cutting it to size with a board cutter. Its nice! I can be rough with my stylus on the screen without worrying about scratching the screen. It's advertised as military spec'ed and seems durable and tough. Only downside is that its grippy so the stylus doesn't run as smooth as it does on the native screen or a more rigid screen film.
I measured the screen to be:
LCD: 3 3/8 x 6in
E-ink: 3 1/2 x 4 3/4in
I cut a template and it seemed a wee bit small so I added 1/16in to the measurements and it fits perfectly.
I'll post UPC if anyone is interested.
OK just got off my lazy butt - the product is called:
Invisible Shield by ZAGG
UPC:843404066766
