Lav,
When I was doing my research on Aussies, I too was stunned at the price tag for some of them. Again, for some people this is their "job", so the operation is very commercial. They only have the breeding operation to make money, and there is nothing wrong with that.
Other breeders are very seriously into championship show dogs. These are always registered, lettered (AKC, etc) and very expensive. While these are some of the prettiest pups I have ever seen, I wasn't looking for a show dog, so I passed on these places.
Be aware though that even top breeders have dogs that don't meet their criteria as a top show dog and list them as "pet" dogs. Unless it is a very unusual case, there isn't a thing physically wrong with the pups, they just aren't elite show pups in the eyes of their breeder. A breeder will be much more interested in making a deal with you for one of their 'pet' dogs than they will for one of their top show dogs. (However, the tough economy effects all but the very rich, so even successful breeders should be a little more open to negotiations right now.)
A couple of the business type breeders I visited turned me off. Not only did they try a hard sell on their show dogs, which I always hate and I am in sales, but they really didn't seem to be dog people. They were doing it for a living, but their operation had way too much of a puppy mill feel for my taste.
I bought Spenser from a back yard breeder, and their entire operation was the guy and his son. They had other full time jobs, but did this because they loved dogs, and it did give them some extra cash.
The mother and father (dogs) were both on site, and I got to spend as much time as I wanted with the pups, playing with them outside their cage. I got to watch them all interact, plus I got a wonderful feel from both parents.
I think your visit to the breeder is a great place to start, as it will give you and your family a great introduction to Aussies. You should be able to see them at work or play. I would stress to the owners though that you aren't interested in showing or breeding your dog; you just want a pet !
I also would strongly recommend you check out the ads in your local paper, or online ads (craigslist ?) to see if anyone has Aussies listed. Our paper usually has 2-3 ads any given week listing Aussies for sale.
