I think if you do decide to get into breeding, that frozen/thawed is going to be a lot more work than live feeders. With the two dozen breeders that I have, I could not imagine taking all the time to thaw out frozen rats then do the zombie dance with thongs getting them to eat one at a time. I buy some rats and breed some. If you set up properly, you can keep the smell down by changing the bedding out frequently.
Before you start buying up animals to breed, make sure you have a plan of what you want to do. What morphs do you want to produce or start with? How much time do you have to invest each week in cleaning, feeding and caring for the animals? Who is going to take care of your collection if you are out of town? What racks do you want to use? What racks will you use for hatchlings?
You will be investing a lot of money in quality racks, feeding, breeding stock, etc., if you do it right. So, take your time and do a lot of planning. Otherwise, you may end up spending money on things that you find later are a waste.
