Experience with generators / aggregates

For some time now I have been working in a great generator especially in the garden (without electricity) or even in camping times… the problem: The part is sour loud in the garden already Nervig because you have to put it completely to the end to have some rest. When camping this is even more annoying. So the consideration of what new to buy. A small inverter should become so 2000 to 3000W power, it should be damped and well transportable. It is best also tank foreign suction zb from a Canister. Accordingly, the would often have continuous operation times run through a weekend etc. Now I don’t know what to get myself I didn’t necessarily want to be in the four-digit range. On eBay classifieds etc there are some Honda EU20i for 500 to 700€. On eBay you can find for about 700€ but also 3000W inverters from Pramac or 2200w from Briggs&Stratton. What would you recommend?
