This right here is exactly why a large, well-established breeder with a good reputation can command higher prices for the same animals that you see on a small or new breeder's table. You're not just buying an animal, you're also paying for customer service if there's a problem with that animal after you take it home.
That doesn't mean a small hobbyist can't provide the same support after the sale - and many do - it's just that without having a good reputation they can't command the higher prices. As Dave pointed out, when you do buy the less expensive animal you're taking the risk of the seller taking your money and running afterward.
