I think you need to be much more specific about what you hunt, how often, how will the dog be housed, can you train etc. I have a very close friend who is French and has a very nice line of Griff's, they are good enough woodcock dogs, but a bit soft for me and not nearly as good in the versatile category as the GSP or the Brit. Because of the small number of dogs being bred, it becomes much more critical that you be able to evaluate both parents as well as the pups. I have seen some become aggressive of other dogs or even children especially if they are allowed to place themselves ahead of the kids in the pack order. Much easier to find a quality Brit, or even a German wirehair if that is the look you are going for.
Range is a function of training and experience. I had an English Setter that you had to follow on horseback when we were out west hunting chickens but would be within bell range in the Appalachians where I live
