You can add sampling memory by adding PC100 or PC133 sticks of ram. I didnt know that it ships with none, thats pretty stupid. Not sure about the mic in thing, im sure theres something that works.

The Fantom-X and Extreme are closely matched. But i cant think of anything that the Fantom doesnt have or exceeds that of the Triton. Are you destined for new or would you buy used? Check Ebay if your lucky you can find really nice great condition ones for 4 hundred less.
