I'm not a professional either. I started using LR two years ago. Before that I used iphoto which at that time I thought was adequate until I realized what LR could do. You could use Photoshop elements. I got it for like 60 bucks. But if you want to spend more time shooting and less time editing you should make an investment and get LR. Don't underestimate the post process. It's as important as the shooting process. It is part of the creative process.
