In reply to Pewtle:
I'm not sure if the cost of gear has outstripped salaries/wages. Winter climbing kit has always been expensive, a niche market within a small market. Like others I started with doing easy routes in bendy walking boots, a single axe and a pair of crampons. For winter walking you only need this much. Perhaps the main problem is that the modern technical crampons do require a compatible boot so you either have to go the whole hog in one go or end up with two lots of kit.
Assuming you've got decent walking boots then getting a pair of crampons to suit and a single axe is all you need to start heading out walking in snow and ice. Obviously knowing how to use them helps, particularly the axe as you can cut steps across short sections of banked snow and the like to avoid having to put crampons on, take them off at regular intervals which just slows things down even more than the general clumsiness of winter walking/climbing does already.
A skills course would be definitely worthwhile if you feel that you've genuinely no idea of the techniques though finding somewhere fairly low and safe (no crags or boulder fields beneath you) and simply trying things out for yourself like cutting steps or ice axe braking is also worthwhile. You might think it's a day wasted but if it's a wild day on the tops then you are building up experience.
