Best Price-to-Quality line for Pure Sinewave Inverters

I have the big Magnum in our living pod (4kW with generator sharing, about $1800) but in the garage pod we use a smaller 1kW Magnum that is pure sine, has remote, and was around $700. Both have been performing flawlessly.

$700 might still be out of budget, but it can do 1600 watts for 5 seconds, enough to start a power tool motor or vacuum cleaner.
