After about 15 years of use, my old B&Q strimmer has started to play up. It starts easily, but clunks & clanks and sounds as if it's going to go 'bang' one of these days. So, I've just bought a nice new shiny one - a Stihl FS50 CE. Nice and easy to start, but uses a different gauge of line than my old one, so I've got a large coil of redundant strimmer line.
I've also just fixed a 'cordless' B&D strimmer for a friend. She found it difficult to use a petrol strimmer so bought a battery one. OK for trimming the flower beds, but not for rough work.
