Obviously they are brokers, not breeders, but it's impossible to tell from the website.

You found out the hard way that anyone can put together a slick website, but it doesn't guarentee the quality of the puppies.
My heart breaks for you. My Lady is a rescue and has a laundry list of health issues. I adopted her at 4.5 years old and she had been healthy up until then. Her genetic "time bombs" started going off shortly after I adopted her and I have spent a fortune on her. I spend $5,000 a year just on medications and routine checkups to monitor her conditions. Unexpected illnesses/complications usually run another $1,000 plus. We've had two in 2009.
Since yours are both puppies, I can't imagine how expensive it will be going forward with two dogs the same age since they are very likely carrying "genetic time bombs", too.
It is very costly to own a poorly bred dog. The financial costs are nothing compared to the emotional costs of loving a chronically ill dog, though, as you found out with your Shepherd. I have been blessed to have Lady for 14 years, much longer than anyone (especially my vets) would have imagined.
