The lay out is nice, simple and easy on the eyes as Katie said. I liked the pictures that were there and your comparison chart for WA.

I do like the lay out of your site, easy on the eyes and to navigate, you could use some pictures read a post recently wished I could remember which member wrote it did speak about having pictures as people are very visual... keep up the good work
