I've heard of the wobble and had looked at YouTube but the results were varied slightly. Is it just when the snake has its head tilted and doesn't seem to be able to move in a straight manner?

I have always had a fascination with snakes so I'm sure the snake bug will undoubtedly take its toll on me as well. If I do end up breeding in the future would a female be a better investment than a male? Would I have to worry about eggs being laid at all if I had a single female for a few years? Also what morphs would be the best investment for possible future breeding? I was looking to keep my budget around $250 if possible for my first snake.
