Best opal shop in Coober Pedy

We've just returned from a fantastic month outback that took in the Flinders Ranges, Birdsville races, then across the Simpson Desert to Ayers Rock and Coober Pedy.
One of the highlights of the trip was meeting the lovely lady - Stella - who runs the 'Discount Opalhouse' in Coober Pedy. When you walk in she will offer you a bowl full of small polished stones and ask you to take one for safe travel. We didn't spend a lot of money, but as we paid she loaded us up with extra little bits 'n pieces of semi precious stone that she has selected from her husbands' mine. Stella is very knowledgeable about opals, she has lived in Coober Pedy for most of her adult life and is quite happy to talk about opals, mining and Coober Pedy, without any 'sell'. If you're going to Coober Pedy I recommend dropping into her shop.

Not as sure about recommending the Birdsville Races as a family weekend though. An interesting experience, with an overload of old blokes from the cities out for a wild weekend with their mates, away from their families. I've never seen so many middle aged guys acting and boozing like teenagers. I guess some blokes never grow up.
PS: I had a win too. And we're still trying to get the prickles out of our sleeping bags.
