Moo.com any good at printing?

I need to find a new printer. Basically just general stuff for a business like cards, flyers, and store window posters.

I have looked around online and found Moo. The website seems good and the prices are not bad. Has anyone had anything printed by Moo and would recommend them or not?

I probably would get stuff printed about 4 times a year (every season). Print quality isn't super important but durability of paper and price are.
