The only thing I can say is shop around. You'll be glad you did. Take an hour, call as many glass shops as you can tolerate to call, write down their price, and at the end choose from the top lowest priced by reputation. I just changed mine last week and the first place I checked quoted me $590. I ended up calling around 60 shops within an hour's drive to get a good feel of the market, turns out that the lowest price was $295 and the highest was $780. Keep in mind, there are very very few manufacturers of automotive glass, most of the time an OEM "replacement" is made from the same production factory as the OEM original glass, it just doesn't meet the strict quality control guidelines for Toyota. Doesn't mean its less safe, less reliable, or of lesser quality. When you're saving 50% by shopping around, it also means you can change it twice for the same amount of dollars.
