work with it? Would a standard VGA to DVI (ADC is on the mac also, but I wasn't sure which was better - I just assumed DVI) from radioshack work correctly, or is there some special "mac only" type of adapter I need to buy? I didn't really want to spend a whole lot of money on this since I used a good portion of what I had saved for the mac itself. The adapter at radioshack is around 14 bucks, and I was planning on getting it today once I find out if it's compatible or not. Thanks in advance for any info .
