In reply to Offwidth:
I started with solid walking boots, one wooden shafted axe, a hawser laid rope, two Salewa screws and a deadman. Plus someone who knew, sort of, which way was up. Survived that (just), mostly thanks to a week of perfect neve and the odd big snow-drift right where it mattered. Got as far as II/III. Army surplus green anorak and corduroy trousers with women's tights underneath - the latter were the result of an administrative error and were warm but had one major shortcoming - it's well-nigh impossible to have a pee when wearing an undergarment without a fly and a waist that comes up to your ribs.
Then graduated to 'student' and acquired proper boots, two axes and some warthogs, a Chouinard screw and some Snargs. Survived that too.
Did some more with axes that worked, plastic boots and footfangs. It became a whole lot easier
Stopped for ten years when the kids were young (and I was skint as a result and had 'responsibilities')
Started again, to discover that ice screws now worked. It became easier again
Acquired axes with handles. Belay jackets became the vogue. It became easier and warmer.
There's even a nice path up Ben Nevis now, instead of a bog
In terms of money saving tips - Decathlon. I bought a new softshell jacket a month ago. Not cheap, big brand, and not that good either as it turned out. In Decathlon yesterday, I paid £30 for a softshell jacket that is superior in every way except that the colour isn't as nice.
