I have spent pleanty of money with pro's training my dogs. I like the idea of a 2-3 yr old trained dog thats ready to hunt. 2-5 K is still a great value for an avid hunter considering thats only about $500 a year for a hobby. Some folks spend more than that on vices.
That's OK by me too. We are not talking "STARTED" dog which nobody has a definite definition for and who is going to "FINISH" it? 2-5 could be cheap. The last question is does the dog get out of the kennel more than few days during hunting season.
