Craigslist: good? bad?

[Likeabosscd]

I currently don't own any snakes but I'm very interested in getting one. I would like to purchase the snake from a trusted breeder but my parents keep suggesting Craigslist. I don't really trust Craigslist because I think the snake will be aggressive, get sick, die early, or just have a bunch of problems. I would also like to raise the snake from a young age rather than getting a full grown mature snake. Mostly, all I see on Craigslist is a bunch of full grown snakes.

Just wondering anyone's opinion on whether or not I should trust Craigslist or if I should just try to get the snake from the breeder.
