Over the weekend I installed a SGe on my Prius which I'm driving daily now. Darin and Ben asked me to do a review on it for the blog. I have it hooked up along with the SGII, so I have both running. I'll be sharing what I learn about it and giving feedback on the pros and cons of the SGe vs SGII. I'll get pictures up this afternoon when I get home.
If you have any specific questions about the SGe or anything you'd like me to try just let me know.
