Catch dog Prices?

My catch dog was a gift when she was just a puppy. She's a large red nose pit and to me she would be worth at least 350. She catches hard but she's also intelligent which I think is important in a CD. She's rough but not reckless and she's also a good dog around the family. I raised her though so I know I can trust her to hold onto a pig and not let go. I used to hunt with a guy that just picked dogs up for free and tried them out and some would catch but many tended to bite instead of catch so he had a hard time finding a 'good' catch dog. The one he finally did find is one of the best catch dogs I have ever seen but it took him a while to find the dog
