Hey which audio card would you suggest out of these 3 contenders? I only have a midi keyboard and would plug in a guitar and possibly a mic that would be it for now..

Maudio? RME? or Echo? If it makes a difference i would be on 3 comps (one giga, one sonar, and one I\'m building for QLSO. My budget I would not want to spend more than 300 for the card
