Why not get one of your studs puppies instead of buying a bitch for your stud (bitch that might not grow up to go well with the dog you have home anyway!)
As you must give you stud out to girls you like, so it would make sense to use this way as a way to get the "next generation"?
Then you would have the line of the stud in your new girl already(which I assume you are after wanting to get a girl that goes well with your stud) and when the time comes, you have all the dogs in the world to pick from to put together with your girl.
