I have briefly looked at other frameworks, but not enough to form an opinion on them. My partner prefers to use our existing library of classes, which I now find a bit dated. We've considered upgrading our code, but I think it's too much work personally - I'd love to spend the time writing my own framework (well, adapting our library), but I just don't feel it is practicle, maybe if we did this for a hobby and not a living it might be different.

The reason I'm so adamant on Zend is mainly due to the fact it's Zend, lol. Seems like a silly reason I know, but that aside, it looks to be the best out there in terms of professionalism and code (again though, that's a rather naive assumption considering I've not checked out all the other frameworks).
