You have raised a number of common points here, Russ.
For many people (the majority in fact) a £1000 camera is just as inaccessible as a £6000 model.
Some of these instructors appear to consider expenses of this magnitude as simply being spare pocket money; like many city traders used to spend their bonuses and are unaware that there is anybody between their level of wealth and penniless beggars.
However, in their defence, I suppose it could be argued that these tutorials need to appeal to as many users as possible so starting at the top level tends to also include the middle group as many techniques apply to all levels of dslr cameras/equipment and the best of the point and shoot group.
There are certainly quite a number of books/DVDs which aim more at the middle market so I suppose it may simply be a case of doing a bit of research and looking for someone who retains 'the common touch'.
But it isn't just photography which suffers from somewhat elitist presenters. I get fed up with many wildlife film producers who show unusual items which have taken a highly skilled camera crew a great deal of time and expense to produce. Then the result is shown in a manner which suggests this sort of behaviour is commonplace and can be seen in your neighbourhood any day.
Give me the 'real life' naturalists who, like most of us, might never actually see these occasional events and concentrate on what actually happens everyday.
However, don't totally give up on the 'good life' Russ, keep buying those lottery tickets.
