I disagree that rats suck and stink. But then again its subjective..... I breed in my apartment and keep a number of my favorite girls in my bedroom. As long as you're using a good bedding and cleaning at least once a week or more, as well as feeding quality food, there is little to no smell.
However, I agree with the rest of your post. It's not really cost effective unless you're producing in massive quantities.
Personally, I don't have that many snakes and it would be cheaper to buy f/t in bulk, but I find that rat breeding is fun and I do it because I enjoy it. I love my rats.
