I am hunting for my second (the first being a stock kit 18-55mm) DSLR lens. I know I want a telephoto zoom, but am unsure what I can get around the $300-400 range for a Canon DSLR? So far, I've found this somewhat useful article:http://pic.templetons.com/brad/photo/dslrlens.html

While you're at it, I am still a semi-noob dSLR enthusiast and wouldn't mind a few pointers at taking better shots :-)
