A Quick Validation Test of PSD to XHTML services

I'm starting up a service in which I convert PSD to XHTML and decided to check out a competitor. So I was looking at one, and I checked if their code validated, it didn't. Then I decided to test other sites, here's what I found. I placed them in order of Invalid to valid. I did all that were posted on http://sentences.org 19 quality xhtml/css/cms providers post. Only a couple came out invalid. The rest passed with flying colors. I pan to analize each of their layouts and post my findings at a much later date.
