I would rate it rather low. The visual appeal of the site is moderately ok, but it could stand for a good bit of improvement. The browser compatibility sucks, they should make the code standards compliant, and I absolutely hate the having two elements (main body and central portion) that both scroll vertically. I'm sure I could find more to [female canine] about if I wanted to take the time.
BTW, I'm not a professional web designer or anything, just have done one website for a non-profit organization, one paid job for a friend's business, and several iterations of my personal website (none of them have ever been finished, few have made it to the web, and none have been posted to a real domain outside of my ISP's personal webspace).
