As Kital says, it costs the same to breed and rear a 'pet' quality puppy as it does a 'show' quality one, so there should be very little difference in price. If you take into account buying the mother, rearing, vaccinations, food, showing costs if it is a show dog, stud fee, feeding an in whelp bitch, vets fees, hip scoring, health checks for inherited diseases etc etc breeding dogs is not a money making game unless you do it on the cheap which is when problems arise.
If you want an undocked dog, be prepared to pay for it if not in advance, as soon as it is born, as most breeders would not be willing to keep an undocked puppy for you in case you changed your mind, because most people want a dog to look like the breed they are buying and undocked Dobermanns look like a crossbreed to most people.
Someone near me had a litter of undocked Rottweilers, she still had eight of them at 15 weeks, because no-one wanted them! She ended up almost giving them away and has said she will never breed another litter of undocked pups again, she thought that was what everyone wanted.
Also most breeders remove dew claws for the good of the dog, as they can cause horrendous pain and bleed profusely if torn.
If you take the life of the dog into consideration, say an average of ten years, at a cost of �500, that is only �50 a year, or less than �1 a week - isn't a well bred healthy lifelong companion worth that to you?
