If you just want meat, broad-breasteds are fine. But they don't fly! If you want fun and variety, get heritage turkeys. They come in lots of colors, fly if you don't clip the wings, and have a body shape that is much closer to a wild turkey. They won't have as much meat, but they will reporoduce naturally for you if you keep a couple over winter.
Depending on diseases in your area, you may or may not want to raise turkeys and chickens together. Check with your local extension office.
Books are full of cautions about how hard turkeys are to start on feed and water. I haven't found them to be any harder than chickens. I do give them extra light for the first couple of days to help them find food. I don't really know if its needed or not.
I lived for chickens until I got turkeys. Now I go out and sit with them for about 30 minutes a day just to relax. I love their noises and they are very friendly.
There is no way you won't have fun with turkeys. I agree with dogfish, butchering your turkeys will be a little heartbreaking.
