Flymo/Electrolux/McCulloch are all brands of the Electrolux group.

We got a McCulloch cheap in an end of season sale from Argos a couple of
years ago and it's been fine, it has another engine brand, can't remember
which - Italian and not supposed to be as good as B&S but starts first time
every time.

I expect the plastic deck will fail due to vibration before the engine dies,
and it does vibrate fairly well when damp grass gets clogged around the
blades. So that would be my recommendation on a cheap mower, get a metal
decked one if you can.
