FIRST in Michigan uses glFusion, it works pretty well. 397 used Wordpress but the site is currently down. TBA uses Tumblr for a good portion of their site. Personally I have used Wordpress and Tumblr. I haven't found any problems with any of them. Figure out exactly what you need it to do and make sure it can do it. Either that or find one of the open source ones and tweak it to do what you want.
