I would direct everyone's attention to post #13.
Answered the OPs question without making him feel like an idiot.
I fondly remember snake keeping 20 to 30 years ago - when we had no idea what a Helix or a Herpstat was, but still managed to keep our animals healthy and happy with the humble rheostat and the *gasp* taboo glass aquarium.
Owning reptiles does indeed cost alot of money when you convince yourself you need to buy a drawer full of $1,000.00 snakes, a $600 rack and a $150 thermostat. With a little diligence you can have the same amount of fun with some $50.00 snakes, a $10 dimmer and a couple of glass aquariums bought used off of Craig's List.
Remember, spend in moderation, get the basics down and when you can finally afford to keep all of the fancy snakes you want and not live paycheck to paycheck, go ahead and go Cadillac all the way.
To the OP - good on ya for getting your ducks in order before you get your snake.
