If it was me I would get the first pup, she sounds great and is gorgeous. It's a bonus she comes from champion bloodlines. Your hubby will fall in love with her when she arrives, it's hard to pick a pup when you can't visit the litter but from what I can see I think she's your best option. This breeder sounds great since she's offering you written lifetime health guarantee and will fly the puppy to you herself.
Just with the health issues arising with the other pup seems concerning to me and that would worry me and this breeder isn't offering you a health guarantee like the first breeder.
You also sound dissapointed with her about the flying situation and if you are uncomfortable your going to be so nervous about it.
Even though there is a considerable price difference, your paying for piece of mind with her health and for the pup to be brought to you with the breeder. It will be worth paying for
