It really depends on your region. With you being in Cali (according to your miniprofile on the left), you will see much higher prices from breeders in your area. I do a lot of research and looking around at litters and talking to other breeders, so I'll give you what I've found in GSDs...
Litters bred in the US from Import or domestic dogs:
Average working line litter w/ guarantees = $800-1800
Average showline litter w/ guarantees = $1500-5000
Litters bred in Europe and pups shipped from Europe (which usually does NOT include a guarantee on hips/elbows/health):
Average working line litter = 500-2500 Euros
If you see something under $500, then it's most likely a BYB or a dog that must be sterilized.
