Suggestions needed for a new audio interface.

Hello to all Recording.org members. I am a real novice at recording. Two years ago, I agonized for months with Cubase LE4 and a PreSonus firebox to record exactly one song. The results were actually not bad, but the process was such agony I stepped away for a long time.

In any event, I would like to start simple recording again, and just tried to hook up my PreSonus Firebox, and it will not connect. I had frequent unexplained disconnections the last time I was using it, and now I am convinced that my Firebox or the software is flawed. I need a recommendation for a similar functioning device (two channel audio interface with soundcard) that works in a similar way.

I would imagine things have changed a bit in the last two years, and frankly, I no longer have the brain power to research like mad, so I would be very grateful for the advice of others for a simple to connect, simple to use, and reliable unit.
