Searching the best mini gas tiller

We are doing some severe space clearing and leveling to move a storehouse unit (aluminum skeleton and dense coated tarp roof/sides). My tiller died of a broken transmission (mini - but got lots of years of use). It was great, but I remember holding many times to stop and get a stone out that would be jammed between tines. Can anybody suggest me the best one?

I would go with the Honda or the Mantis.
