For me I'd rather pay more for a morph from an established and respected breeder.

I don't mind the extra cash for a snake I know is from good stock, has a traceable history, and for the customer service in case there is an issue with a snake.

Sure you can pay $150 for a mojo from some dude online, but how sure can you be that the snake is healthy and illness free. Often you may find that once you have bought the snake and something negative with it crops up that the response from the seller is "Sorry for you".....
