I'm looking to buy a small inverter to power a flat panel TV and a satellite box. Would a modified sin wave inverter work or do I need a pure sin wave inverter?

It's all an individual match with MSW. Some work, some don't. Myself, I wouldn't risk my expensive electronics or my enjoyment of same to save a few bucks with a cheap inverter.
You see, if you get the PSW there is NO risk.

Slight correction, it is a sine wave. No sin involved.

That's better than sign wave. And sin is the abbreviation for sine (as if it needed one)

Really depends on the electronics and how they match up. I had a diesel Bounder that had a MSW inverter in it and we had some troubles with our Directv on certain channels. A small MSW cigar lighter inverter worked just fine. To be sure use a PSW inverter unless you're feeling lucky.

I have never had a problem running any electronics on a MSW inverter. They are cheap enough you won't lose much if you have a problem with it which I don't think you will. I wouldn't spend the dollars to buy the PSW if I didn't have to.

Listen to 2oldman. His advice is right on the money. It depends, but I wouldn't want to risk my electronics on trying a MSW and finding out that it didn't work.

I have personal experience with electronics being "fried" by MSW inverters. One of my employees destroyed his Apple laptop by plugging it into my modified sine inverter. Also, one of my customers, after I warned him not to, ruined the electronics in 2 gas ranges from Lowes before he figured out it was the MSW inverter in his cabin causing the problem.
For my money, with electronics, get the sine wave inverter and know that it will work properly.

Hi,
For a TV that is a low wattage device, not much money will be saved by going MSW. The chances of video signal interference are not low. For those reasons I'd go PSW.

A good 300W PSW inverter costs $160.
