Looking for a decent Laptop warranty

I just picked up an Acer 5720 laptop. It came with the usual 1 year warranty. I would like to get an extended for at least 2 years and an accidental plan would be nice too. Acer offers a couple options 2 or 3 year, but no accidental, and the reviews for Acer support aren't that great. Square Trade looks very good on the surface but some of the reviews are mixed. Most of the issues with them stem from refurb warranties so tat wouldn't be an issue for me. I am just wondering if anyone out there has had good or bad experience with any specific warranty companies.?.
