That's a good deal if they're 100% healthy, etc. You know the old saying, "if it seems too good to be true, then it probably is". But if you trust him could be a good deal.

As for breeding, you can breed them with whatever you want to corn wise. But you would still need to label the babies as hybrids, it would be dishonest not to.

As for whether or not you should get them, that's up to you. One thing I've learned is that I only now get snakes that I'm really pumped and want to work with, not to get them just to get them. So if you really REALLY want them, then go for them.

But if you're thinking of getting them, more or less for the sake of getting them, then I probably wouldn't.
