Codeigniter was the first php framework I learned. It was really easy to understand and extend. However it just doesn't feel right and I'm starting to think I'm just tired of php. I've seen bamboo invoice before. There are a few other robust projects I've seen but nothing that you could compare to 37signals apps or github.

I also started using CodeIgniter and i also had, at some point , the feeling that it "just doesn't feel right". If you want to learn a new language i'd probably go with RoR otherwise take your existing PHP skills and use Symfony 2 (http://symfony.com/). It definitly has a steeper learning curve than CodeIgniter but i couldn't think of a single point why i would prefer CodeIgniter over Symfony 2 now.
