The pixel offers a $99 replacement plan, plus an additional $99 every time you replace the phone, up to 2 times. I think it lasts for 2 years.
If the only thing holding you back on getting the phone is being able to get it repaired, the cost difference is $70 or $50 the first time you break your screen, and $40 or $0 the second time, and the plan covers more than just broken screens.
The biggest downside is that you have to front the $99.
