How much should I sell my Dachshund puppies for?

I have two pure breed dachshund dogs. The father is AKC papered the mother is CKC papered. They had a small litter earlier this year, and I gave them all away to good homes. I was told by many people later that I should have sold them because they are very expensive dogs in this area. I looked into the average price of them in my area and they usually run about $499.99 per puppy. I feel this price is outrageous, and I don't feel comfortable ripping somebody off like that. I now have 3 adorable puppies that are 3 days old that I would like to find good homes for. I would like to find a price that would be both fair to me, and fair to the puppie's new owner. Please help me out on this one! (Also, the mother and father are not registered…I have their papers but never registered them)
I am going to get the mother fixed after this litter is weened. I let her have one litter because I was asked by so many people for puppies. I don't want to sell them, because I feel wrong selling pets, they should be part of your family. I am just unsure of the proper solution. I have local breeders upset that I am giving away puppies that they are trying to sell, but I feel morally wrong selling the puppies for any price at all.

what you have is pet quality dogs not for breeding. so if you sell for any price you will be ripping people off.
an akc and a ckc puppy can't be registered if i remember right.
