I bought the same PV1250 Mr Wizard has at his recommendation. It doesn't make the chargers or satellite box hot like my PowerBright MSW inverter does. It doesn't add lines to the flat screen TV either. It has a BIG fan, not some screaming mimi and it starts that little air conditioner so smooth that I have to check the Kill a watt just to make sure the compressor is on. $200 on ebay delivered.
I wish I had talked to him before buying a cheap PSW unit. It would have been fine just running the microwave, coffee pot, cooktop, hair dryer and more. That little A/C starting was just too much and poof...there goes $200. Still, for the rest of the stuff it was fine.
Lots of options to fill your needs. I'm glad it didn't cost me a arm and a leg to fire up the A/C once in a while.
