I'm cross--posting to DIY and to Gardening.

I have had two Bosch AHS 55-26 (corded) hedgetrimmers in the last 10
years. I cut a lot of hedging, in three different gardens, and this is a
great cutter: 55cm blade, 600W power, and weighs 3.6kg; my second one
cost me about £130 several years ago. Used sensibly, nothing stops it
blazing through the many different hedges I look after.

I'm starting to get older ... hang on: I've always been getting older:
what has happened is that I'm starting to _feel_ older, and I'm
wondering if a cordless (therefore lighter) trimmer will be kinder to my
now-rapidly declining body.

Does anyone have reasonably extensive experience of cordless trimmers? I
can't really believe that even the best cordless trimmer could match the
power of the one I have.

Opinions would be most welcome - TIA
