Title says all. I'm going to buy the next iteration of the 12" MacBook whenever it's announced, and one accessory I will definitely be picking up is a USB-to-monitor dongle. The thing is, however, I would like the ability to output to both VGA and HDMI (not simultaneously, obviously). I know that Apple offers USB-to-VGA and USB-to-HDMI dongles separately, but I figure I would try to save a bit and instead, buy a USB-to-VGA dongle from Apple and a third-party HDMI-to-VGA dongle. Would that work just as well, or is this going to be a case of "you get what you pay for"?
