GitHub has just become so ubiquitous, you start to forget other source control systems are out there. If I wasn't still using SVN at work, I'd be in git all the time.
I personally host a perforce server on google compute engine for around $15 a month (g1-small + whatever size persistent disk you want). Relatively easy to set up (they provide repositories for ubuntu and fedora iirc), configuration is largely interactive when setting up or through the P4Admin tool (which allows you to very easily setup permissions, depots, etc).
I know that isn't fully managed like github and doesn't provide issue tracking, wikis, etc, but I've found it fairly easy to deal with if you know a bit of how to setup a linux VPS.
I did not try this though.
Which aren't bad, but may not be what you're looking for.
