At the begining of next year, my dad is getting a bonus and giving me and my sister 1000$ each to do whatever we want with. I would like to use mine on starting breeding snakes as a hobby and to supplement our income. I'm patrolling craigslist for adult and hatchling racks. I am going to be producing blue eyed lucys, black eyed lucys, or ivorys, hets for them, some normals, and eventually all of them. Should I start with a pair of mojaves, yellowbellies, or fires? Also, what is the best thermostat for multiple(2 or3) racks and one heat pad?
