I was wondering if anyone could gimme some advice on buying a "mini-displayport to VGA adaptor" for my MAC BOOK PRO 13" to use with projectors for presentation purposes. The Apple price for the product is $29 while I can buy it cheap from Amazon. However, many reviews are against buying the $10 Amazon product as its inferior to that of the original Apple product. Any suggestions other than Amazon?
I'd also like to know about the quality of "Mini DisplayPort to DVI Adaptor" compared to VGA. I don't know if they are also widely used in projectors. Thanks.
