Sometimes having a champion parent may just be about making the litter look good to sell and the parents are not a good match.
other times a pedigree may have parents that are not champions, but go producers or simply young, but their pedigrees are full of 'quality' which people in the breed will recognise and that litter would be considered far superior.
In my breed pups are basically the same price across the board, but then you expect the parents to have all required health test and be bred with the aim of producing quality.
Breed club advise should steer you right. Also if you google the parents names you should have results for shows/trials/health results come up, so even if they are not the most successful they may well be very worthy and proving it.
Sadly this is a breed that has more and more moved out of being primarily in the hands of the true enthusiasts and more people interested only in their ability to reproduce and sell easily are breeding.
