Just remember, if you crack it, you buy another one. If the glass people crack it, they buy another one. And it can be tricky--there's definately an art to it.
Safelite just did mine--they had a guy who did all 911's in the area, so he had lots of practice and got it right the first time.
generally glass replacement does not affect your insurance rates--I paid the deductable.
