A lot of talk about pricing here, so I add my favorite www.thum.io - charging $2 for 10.000 with first 1.000 for free.
What I like about them in particular is their buffering: once a screenshot is made, it can be served from their server 'unlimited' times without counting as a new screenshot.
A real improvement on their service (worth paying extra for me !) would be a way to dismiss the banner on github projects for new visitors. Obviously their browser is not logged into Github at the moment of the screenshot, so those screenshots mainly shows a general Github welcome banner :-(
