Morrus, you could always contact James of RPG Host. He has some good ones on the messageboards he hosts (not least of which is the Emerald Night theme ).
Evolution is good, a big improvement over the "light" style. Trying to get use to the boxes around posts, but otherwise it is excellent.
Once you set them up, is having options for styles any extra trouble? It is very nice to be able to switch around. If I am reading a long storyhour my eyes tend to get tired, and being able to switch styles seems to help.
Is it just me or do several of these styles leave an inch or so on both the left and right sides of the screen. As a result eveything seems to get squished in the middle. Any way to fix it?
