Recommendations for a rotorvator for a small garden?

Morning all

I'm looking for recommendations for a rotorvator for a small garden.  Preferably something not too heavy as I will need to lift it up and down 4 steps from the store to the garden.

Other things to take into consideration is that I've never owned a petrol anything before (well other than my car lol), so something very simple and straight forward to use would be a bonus.

I'm in France, so may have different brands available, but most of the "big" ones are here (Al-ko, wolf etc).

TIA

If founds allow for it:
Mantis.

You will never regrett getting one of those 

Bought mine in 1997:ish. Still works better than the US-ads claims
