Do electric lawn rakes / scarifier work?

Question:After having tried to rid my lawn of moss by hand with a spring tine rake, I'm considering getting a electric rake to take the hard work out of it.

I only have two smallish lawns, so couldn't justify spending more than £60-£70. That would get me a black and decker or bosch one.
Are these any good?
Do they break easily as it would be working a lot harder than a lawn mower.

If any one has one of these it would be helpfull to know how you find them.

Thanks

I think you should rent one first to determine if the tool will do the job you have in mind. Trying a couple of different brands and perhaps models will give you quite a bit of hands-on information. If they don't work as you imagine they should then you will not be stuck with a machine you don't want. And then you can go to plan B what-ever that might be.
