That's good that you're being a responsible pet owner and doing your research before purchasing anything. Though you can always save your money and not buy that book, because we have wonderful care sheets on the forum. Then you can always ask any questions you have as you'll get first hand knowledge from many people who have been keeping for quite some time. They also have a nice DIY section towards the bottom of the forum which can help you build a rack system or a tub system, whatever your needs are.
As far as getting your eye candy and wanting to stay under $200, you're going to want to stay with a single gene snake, meaning nothing fancy. Most of your double gene snakes like the bumblebee will be past your $200 price range. Though if you attend a show you may be able to pick up a male hatchling for something near there, money always speaks at shows but please don't take me as meaning to low ball somebody. Say something is priced at $225 or something, offer him $200 and in most cases they're willing to go lower at a show and you save on shipping. Spiders are nice light morphs as well as pastels and both can be acquired for under $200, just for a heads up a male will be cheaper then a female.
