UMC404HD : Probably the best in the price range

I am very satisfied with the quality. Durable metal body, reliable, the plastic parts aren't fiddly, it has got low latency and low noise levels, good preamps. I have been using it for almost 3 years and haven't had a problem with it whatsoever. The great thing about it is that it is so small I can take it from my desk, throw it in the bag and take it anywhere with me to record high quality sound outside my home studio as well which I have been doing for both - music (small events) and film projects. And the build quality is so good that I don't have to worry about it too much either.

The only thing I would like it to have is a power button. There are easy workarounds, but still would be nice if it had a dedicated power button on the unit, which is why it gets 4* in "features".
