Which soundcard/audio interface is best for live VST use with a Laptop?

[DarylWise]

I am choose between the M-Audio Fast Track Pro

or the Creative Sound Blaster X-Fi HD USB Audio System

I just need to play my VST's through a good sound card to my Roland amp with good sound.

I use these,  that are pretty good. Nice rugged construction that wont get banged up in your gig bag.

A little less expensive then the m-audio.. They are versatile for digital recording as well.. digital ins and outs,analog stereo outs,  midi, guitar and mic inputs...sound great....

ive run two of them for four years and theyve never failed me.
