a nice modified \ pure sine wave inverter from ebay \ aliexpress for 50$.

[xReM1x]

does anybody know or have any suggestion for a good sine wave inverter (modified sw is fine, it is going to be used on lamps and chargers..)
the RMS wattage needs to be about 500-1200W. I know I cant get a brand name high quality one for 50$ but it is just for fun basically.
ebay is very recommend. I cant get from amazon.
