Great advice all around from some people that know rodents. All in all it boils down to how well you take care of your rodents. If you want a setup and forget it operation it won't ever work. The more time you spend with them and taking care of them, the better it works. I have more time than money right now so breeding my own make sense. Just because it is less expensive doesn't mean that there aren't other trade offs. Good luck with your decision!
