Can anyone recommend a good air compressor/pump? Its gonna be primarily used for keeping tires at the right pressure. I'm pretty sure thats the only reason it's gonna be used for. I bought one of those 12v stick in the cigarette light compressors, but it seems to take forever. I know that I can go to the gas station and use theirs for free, but I have 6 cars in the family and my pops wants me to find a compressor/pump cuz he read an article on how tire pressure effects gas mileage so if you guys/girls could help, it would be much appreciated. Also if I should buy it at kragen/pepboys or if there's an online retailer u can give me the link for. I don't really know what a decent one goes for so good ones per price range would be nice. Thanks again.
