Must be the credit crunch.
Or maybe it's just that I have other better things to spend my money on?
If I wanted to buy a brand-new-shiny van and an off-the-shelf system I could; cash; but I prefer to leave what we've got in the bank/mortgage; we've got one of those mortgages we can dip into - or overpay; and to be honest, I prefer to overpay than spend it.
Anyway, I've re-jigged my pole, total cost so far is £20 and I've a 20 foot light-weight pole; I'll have to spend about another £20 on a light-weight brush and an angle.
Cost in time about an-hour, but next time I do it, I reckon about half-an-hour. It's just my 'learning DIY pole', so I guess I'll spend more, but there's no way I'm going to spend £500 on a modular carbon-fibre pole that's no better (I suspect) than a £60 DIY job.
I read the forums and know guys who've had just the same problems with expensive off-the-shelf poles as those with cost-effective DIY poles.
Sometimes I think some window cleaners have more credit than sense.
Anyway, it looks like the weather's brightening up, so I should get I bottom out and do some work!
