lightroom 2 is legit. if you spend most of your time in camera raw, then definitely go with that. it's fast, powerful, and flexible. there were some early bugs, but those have been ironed out. i have both lightroom 2 and CS4.. if you have photoshop CS3, you're not really missing out on a whole lot with CS4. it's nice, but you'll find a lot more refinement to your workflow with lightroom.
