Which suggests getting a small one until you know what your uses are.

True sine $$$ and only available in larger sizes, maybe not so efficient
but otherwise highly desirable.  Modified sine will put a buzz in many
audio gear (with inadequately filtered power supply), will maybe put
crawling bars on a CRT monitor, will often make small power supplies
hum/buzz, and may give less torque from motor-driven stuff because peak
voltages are a bit lower.   However it suffices for the bulk of uses and is
WAY cheaper.

>Load? 200 watt or 1KW or more?

Figure ten amps input for one watt output -- 200 watts consumption will
draw about 20 amps from the battery, a kilowatt will draw about 100 amps.
