For folks who haven't operated an excavator, the trade-off with these mini-excavators isn't necessarily that they're underpowered. There are two other problems.<p>First, they are very wobbly and you're gonna be limited by that. You really need a fair amount of surface contact and a robust counterweight when you're extending the arm and moving boulders, pulling out roots, or digging into hard soil.<p>Second, you might look at specs and say "oh, cool, digging depth of 5 ft, I don't need more!". Except, this is attainable in one specific (and awkward) position of the excavator's boom and arm. It's less than that across most of the movement range.<p>Another thing to keep in mind that this is not like buying a car. An excavator or a tractor deprecates far more slowly, and many private owners keep them for 20-30 years. A diesel excavator will need DIY maintenance and simple repairs, but it should hold up for life. Battery-powered equipment will probably need new battery packs before that. Just something to keep in mind when figuring out the pros and cons. If you're in the suburbs, noise is a concern, but then, you honestly don't need your own excavator...
