Yes and yes. I knew more about Chances R back when Chance was showing, but it looks like Copper Ridge, Copper Hill
http://www.copperhillaussies.com/index.html and Chances R have similar looks and share some of the same dogs. All three also have a fair number of herding and agility titled puppies as well as dogs listed on OFA.
It doesn't hurt to have a long (more than a year) conversation with a good breeder or two. You can learn from them and they can learn about you. They can mentor you about what to look for and what to stay away from, you can learn their philosophy on breeding, choosing mates and choosing puppies as well as training tips and more.
You never know- they may end up showing at your local show and you can meet them and their dogs. If conversations go well, you *might* end up with one of their puppies or they may have a better suggestion *for you*. Dogs are not "one size fits all" and the dog who you like the looks of may temperamentally be a mismatch. There are many breeds that I like how they look or act but would not want to live with one. And some that would take a while for me to love the looks but I adore their personality.
