| Hi, I am looking for an inverter to produce 120 v for some
applications like refrigerator, air conditioning, micro-wave and some
others applications. I didn't have good experience with a cheap
inverter because the applications didn't worked properly and I am
afraid of breaking something.
I know that my inverter is a sine wave modified and a pure sinewave is
the best but I need to produce 1500W and don't want to pay so much.
Are all the sine modified signal all the same quality. Is there a good
brand for my need ?

First, you have a modified square wave inverter, and no they are not all the same. Some will run
things that others will destroy. But hey, You get what you pay for.
I doubt that a 1500W inverter will suffice, oh, it may well run everything, at least up to the point
where two appliances try to start at the same time.
You would be well advised to do some serious home work as to what the real load will be. i.e. a
complete energy audit of what you want to run.
At least then you will have a known load to calculate from.
You can spend your money how you like, on a quality inverter or new appliances as required from time
to time, pick the wrong inverter and you could be buying a new fridge every month.

Models like these are popular
http://www.beyondoilsolar.com/outback2000.htm
http://www.beyondoilsolar.com/xantrexswplus.htm. All of them are
reliable, have built-in chargers and will be safe for your appliances.
If you don't need a charger then this is probably your lowest cost
option http://www.donrowe.com/inverters/puresine_1500.html. I don't
know how reliable they are.

Heartland America has a 5000 WATT one for $400

FYI: Samlex is a high-quality maker of telecommunications power supplies.
I use their stuff all the time at my job. In today's market they are probably
my first choice, but I have never had occasion to buy any of their inverters.
