One minor thing, I did a wireless card 1510 search on the Dell site and they actually list 4 cards that all have the same manufacturer number but different Dell product numbers. They look identical to me but do list them for different machines. Is any one of them not correct? The Dell product numbers are: 430-3127, 430-3167, 430-3133, and 430-3130. But like I said they all list the manufacturer number of W750F. I'd rather spend the few dollars more and make sure I get the right one off the Dell site than take a chance with ebay.
