Here's one of the websites I designed and maintain.
Textraw | Synthetic Straw
Textraw | Synthetic Straw also points to it.
we get about 1500 hits a month right now. Not too bad I don't think. we're top in google for searches "Textraw" and "Synthetic Straw" also a search for "pine straw" shows our google adwords ad on top in the right column, and we're in the regular results #6. I'm pretty proud of our google stats, as most of our vistors get to our site through search engines.
I do my best to stick to web standards, but honestly I can't tell you if it'll pass all valid xhtml and css checks, but it should be close...
And yes I know the lightbox javascript stuff is overused, but it's quite helpful and appropriate for this site. Also, with the exception of the comparison chart, the rest of the site is table-less.
Oh and I know I'll get yelled at for the typeface of the logo, but I promise I had nothing to do with it and argued and argued for them to change it, but the guy who created the product wouldn't budge. He loves it for some reason.
I put in a good bit of time testing it in Firefox, IE6, and IE7 and even took at look at it in Safari, also checked out most resolutions, and it seemed to test pretty well. Also should print fairly well as I've got a seperate stylesheet for printing.
