Wanting to upgrade soon, but it's a decent little unit with good pres and converters for it's price.
At work we have an RME multiface and an Apogee Symphony system for logic, I sometimes am able to use those for recording and then bring it home (the audio that is, not the interfaces, although I have used the RME interface a bit as we were broken into at work, so I sometimes take it home on a weekend to prevent it being stolen).
I also have an Echo Indigo I/O card which I sometimes use for mixdowns as it's latency is really good and it can cope better with big projects on my laptop as my firewire chipset is a crummy Ricoh and not optimal performance wise.
