I have been using for almost two years now Unfuddle.
It's excellent. It does SVN and GIT hosting, does not skimp on online space, has bug/issue tracking built-in (can import from Trac) AND integrated with the SVN, has wiki, mini-forums, time-tracking... yet it's very simple to use and has non-geeky interface.
It also has a clean API. I do the backup (they do it automatically as well, but I'm super careful with my data) via a simple Powershell script.
They are very customer-oriented: once I needed them to import a SVN repo I had from before and they replied and did the work inside a half-an-hour or so.
There are several levels of service offered, from free to moderately expensive. I'd say overall prices are very reasonable.
I have nothing to disclaim and am in no way affiliated, just a very happy customer.
