I second the above comments. Sweet Maria's is a great source of info and my primary source of beans. Remember that different varietals can roast very differently. It's good to take notes. After much experimentation, I bought a Behmor 1600 roaster and now have a regular routine. Yes, it's time consuming, but I love the relaxation of being outside, sitting patiently, and listening to the roast. In very cold weather I sometimes buy roasted beans, but my results are so much better I go back to roasting as soon as the weather breaks. Roasting is certainly not for everyone, but for some of us it's rewarding.
