You missed out http://www.mypunbb.com, run by Connorhd from punbb.org. They have afew security issues last time i checked as they haven't been upgraded from 1.2 to 1.2.5 as they should have, but other than that it is the best around in my opinion - since invisionfree gives you a dumbed down version of ipb, with massive adverts - this gives you a full version, with no adverts at all.
