While I agree with what you are saying overall, having purchased a dozen or so chameleons from the Kammers over the past 15 or so years, I do feel like I should speak up about my experience with those chameleons, as the inference here is that they may be somehow less than excellent.
Straight up- if you don't know because you live in a country where you can't see for yourself by purchasing one or at a show, then you shouldn't infer things about someone else.
Their chameleons were always easily the healthiest lizards I have ever purchased from anyone, anywhere, at any time. And I've purchased quite a few over the years and am not comparing among small numbers like say a few dozen individuals. There was a *visible* easily discernible difference that made the superior quality of their lizards an absolute joy to own and work with. The cost was a little more, but the lizards were always first rate, perfect condition, healthy, well started and trouble free after purchase. The peace of mind that came from knowing that the lizard purchased would arrive every time in this condition was well worth the purchase price.
Secondly- I'll disagree with the issue that simple and excellent are mutually exclusive concepts. In fact, usually excellence comes from simplicity, not complexity.
