Hello, (Note to Mods: If this is in the wrong section please feel free to move this thread.) I need to purchase a new power inverter in order to use my MBP in my car. Here is the hard part: I've gone through a few cheap ones from Walmart and Radioshack, but they are usually very loud to begin with and when the bearings on the fan that cools them wear out (usually after only a few months of use with all the dust and dirt in an automotive environment) they get REALLY loud and obnoxious. I am looking for an inverter that can do at least 200w RMS, but has no fan. I have tried to use my google-fu pretty extensively on this one but have not turned up any results. Has anybody come across such a thing as this? Thanks alot!
