There's not really too much of a limit to the budget. I like nice green ones with yellow or blue sides. Blue bellies are cool too, and blue dorsal stripes. I don't really like high-yellows, high-blues, melanistics, or whites. I do know that biaks are usually pretty yellow, I was asking about them to see if I would need to worry about size. I prefer dark red neos and I prefer my snakes larger. I also like the brighter, almost neon, colors.
