Some good reading and advice here on how to approach buying for your breeding projects (among other topics). It is a well written article that makes absolutes sense.

Buying males to start off with is a backwards process, especially an adult male when you have no females. All you are going to do is feed him for a year while he loses value- were not talking a lot of value since it's a common variety single gene male. A medium rat every other week is going to set you back $50 in a year. I would pass on the 1.0 Spider at this point and pick up whatever single gene female that fits into your future projects, you and can afford. A 0.1 Pastel of any size would be a good pick-up to start with and probably equivalent to the cost of the male Spider. Hatchlings can be found for $125 and I just picked up a breeder sized 0.1 Pastel for $550 for this year.

Something to think about.
