About PSU, What does it matter? sine wave or normal inverter?

This have been bugging me for a while now, what are the real facts that matter between these two... because the sine wave costs about 100 euros more here ;/

show some facts and what people use themselves.

MODIFIED SINE WAVE is a sales term used for a modified square wave type of AC power which is not quite the same as power company electricity. Modified wave inverters are lower cost, slightly more efficient, and almost all appliances work fine with them, though some may hum louder. But a few sewing machine speed controls and some Apple computers have difficulty on modified SineWave. It can also damage photocopy machines, laser printers, and some cordless tool rechargers. Recently we found the first TV that would not run on any modified wave inverter. Battery chargers in the DR model modified waveform inverters may require the highest quality generator (about $3000 and up) to charge effectively.

TRUE SINE WAVE inverters supply power of better quality than the power company, and work correctly with any appliance. Battery chargers in true sine wave inverters work well with any generator. Xantrex SW+ series and Outback inverters can automatically start and stop a generator when extra battery charge is needed. A low cost Samlex true sine wave inverter might be used when you have just a few smaller appliances that require true sine wave power.

of course this is baised, but eh w/e, you should've searched first, and should still anyways.

edit: the company sells both true and modified sine wave inverters.

And that means that im ok with normal inverter for a carputer, and some basic electrical items i might use...

that means im going to buy 300W inverter that doesnt use sine wave
