I am sure the dog probably is not going to make a good gun dog but he will have had training in the field which is worth a pretty penny in and of itself.
Quality dogs can be had for less that $500 but I think those tend to be more the working and hunting dog varieties which is what we are wanting.
One advantage to all this looking, he now knows exactly the type of dog he wants. We had a GSP before, one we found in our hay field. She was a wonderful dog so we will go that route again.
