When i needed replacement glass on our 2008 Sunova for our driver and passenger windows (fogging) I went with lippert:

Prices were fair and prompt shipping. They do charge a few $$$ extra to pack and ship, but I swear I could have probably driven over the box with my car and not broken them they were so well packaged.
I chose to swap the glass out myself (not that difficult if you are somewhat handy, I can post how to do it) but I believe they also offer install services.
Hope that helps.
