I don't see it as being as bad as many in here .. He sounds like a pretty bright guy with his head screwed on , if he's speaking from his perspective and experiences it should be seen as just one persons's viewpoint and not THE definitive one . It all depends on where he got his information from about the available rack systems and the ' ball python market ' he talks about . He's maybe just badly misinformed .
That said I'm in the UK and know nothing at all about rack systems ..
