Howdy Alex,
Look at Bull Terriers(the Spuds McKenzie dog). The are the "Clown Prince" of the dog world. There is also the miniture Bull Terrier. Rayson has some and he can tell you about the breed. He also has a website with some nice pics of the pups. As far as prices on purebred dogs you have options. If you are not going to show the dog then try to look for a legitiment breeder and ask if they have any "pet" quality dogs.
