I use an Echo Indigo IO for my music production stuff. After more than a year of use, it has never caused me any problems and remains solid and sounds great.
Whether u are using head phones or hooking it up to audio monitors, it is fantastic, has small form factor, and provides crystal clear audio and very low latency with its wdm/asio drivers.
The output only model goes for about 100.00 with the in-out about 180.00. It is a definite 100% awesome buy. You should have no reservations of getting the Echo product.
