I got a sweet deal on an 1800 watt Xantrex modified sine waver inverter with a built in transfer switch. It was 1/4 the price of a similar pure sine so I went for it. Seems to work fine. Used it a few times for the kids to watch a movie. We just have the 23" tv that came with the trailer so its not like we use it for much or really pay attention to the picture quality, but it seems fine.
I also have a cheap 400W modified sine wave in the truck that I have powered the laptop and phone charger with. Also works fine.
I read all the reasons why pure sine is the way to go, but I just could justify the $$. My main goal was to get one with the automatic transfer switch and remote display. I got the inverter, 200 watts of solar panels, the charge controller, and all the other pieces and parts for about $650. Less than a generator, and works good for what we need. I really like having everything hardwired so that all of our 110V outlets switch to the inverter automatically.
And, in searching for a deal on an inverter, I found new or almost new ones go pretty quick on e-Bay. Worst case, if you tried the modified sine wave and your tv doesn't like it, you can probably get 75-80% of your investment back and buy a pure sine.
