As for myself I use a Canon Rebel XTi, It's my first digital camera. It came with an 18-55mm kit
lens and a 70-300mm zoom. I sold the 70-300mm cause the quality of the pictures was poor.
So I bought a 70-200mm f/4 L series lens, best money I ever spent. The quality of the images is outstanding. For all you Canon users L series lenses are by far the best, expensive but well worth the $. I hope to upgrade my camera to a 50D sometime next year and maybe a nice macro lens. As far as prime vs zoom, there's no doubt that prime is way supperior but Like I mentioned my 70-200mm L f/4 is an outstanding lens.

Hope you all have a great day. :)
