I am using Jenkins, started on Hudson. So far, it seems like it has promise. I am not a build engineer, but a jack of all trades, so my background is not deep in this area. I am using it to build some Perl modules, and it is doing a very good job (remember - no previous experience to compare against).

I believe that it prefers jUnit testing output, so you will need to use a newer version of the testing harness with a junit plugin.
