M-Audio M-Track DUO

I've had this interface for around a year, it's pretty good for the price, there's just 2 issues:
For most dynamic microphones, this interface cannot produce enough (clean) gain to be usable without extra gain via software
After 8 months suddenly input 1 started producing a bunch of noise and the volume indicator LED would flash a lot, a week later the same thing happened with the second input and its LED so it was unusable and I ended up getting a higher end interface during Christmas

If you are just starting out as a musician and on a tight budget, this isn't a bad option but definitely make plans to get a higher quality one down the road.
Another thing that I didn't even notice until recently was that the Solo version of this interface actually has a 2nd input in the form of a 1/4" (guitar cable) plug, so if all you need is a mic and a guitar plugged in at the same time, you might as well save a few bucks and get yourself the solo version!
