Anything ...whether it is a dog or a piece of furniture , is only worth what you want to pay for it IMHO
I would say that the £500 one is overpriced simply because it is a fair bit over the price of the others...but then you need to look at what you are getting for your money...the breeding that has gone into the pup , the after care that you can expect to get etc etc
The fact that one pup has Champs in its pedigree means not a lot unless the champs are its dam and sire ...AND you are wanting to show it .
