In reply to Indy: Not sure about repair but screen protector could be anything as it's not touch screen, you could try Google like i just did and find out that Amazon sell a pack of 6 of them for the Edge at £1.64
In reply to Indy: It's a pressure based touch screen so any will do. If you search for 'Edge 810 screen protector' on eBay about 1000 items will come up
I think the one I got was a Vikuiti (3M), can't fault it. It cost about a fiver. Mine has been on 3-4 years (well since the 800 came out) with no issues
