Yeah, the new Online Casinos list is way awesome. And as far as I know, every online casino has roulette. Just follow Lucky13's instructions and click on the "Accepted in United States" link. Anywhere should work on that list.
and if you are accessing from United States, you will see a link "Accepted in United States". Clicking on this link, you will be able to see a list of online casinos that is only accepted in United States.
Same is for all other countries. If you are accessing the site from Spain, you will see link "Accepted in Spain" etc...
This list is recently updated an if not 100%, then 99.99% accurate.
