30mm looks good - i have wanted to get something near the 1.2  - 1.4 range for a while now - looks like another one i might consider. (Just invested in a new computer for processing so wont be afording a new lens any time soon)

Without going through my laundry list (if really that interested go to my homepage where it is listed), there is only one answer to the original debate:

zoom - convenience
prime -better quality of resolution/picture quality (note i didnt say photo there - the prime sat on your camera may not be the right choice of focal length for the photo you are trying - hence the above use of the word convenience) 

How you decide on the use of each depends on your priorities for the reason you carry a camera.  In the words of Alexander the Meerkat "Simples!".

"In every colour, there's the light.
In every stone sleeps a crystal.
Remember the Shaman, when he used to say:
Man is the dream of the Dolphin"
