Almost a year ago I bought cheap, pure sine inverter on ebay.
It is rated at 4000W peak and I am using it to power my refrigerator while driving and coffeemaker or ovens whenever I need them.
So far I put ca 100 hr on it and it does the job. Since I have long cables, running oven will trigger alarm after few minutes and that is the moment I have to start the engine for extra power.
So the only benefit of spending more than $96 for higher-end inverter I could see is slightly better efficiency, but then there is no easy way to measure it.
Funny part, inverter come with factory cables about 2 ft long. They are #8 wire.
I am also observing inverter/chargers as those would simplify converter and transfer switch setup, but those still keep high prices.
