I've seen a lot of topics and replies talking about the PreSonus Series Firebox, Firepod, Firestudio, but no one really talks about the Focusrite Saffire, LE, and Pro or the M-Audio Firewire Solo, 410 and 1814, and the MBox 2, mini and Pro?

So I'm just asking what do you think about them?

Judging on about every aspect of a Firewire interface :
-mic preamp quality
-converters
-price
-included free software for monitoring
-compatibility
-ease of use
-longevity
-reliability
-ins and outs
-whatever else you can find...
