Anyone Have M2Tech Gear? Looking for opinions

I'm thinking about getting M2Tech gear The Evo Hiface Evo 2 USB to SPDIF adapter with the optional clock and power supply. I have a Berkley Alpha USB but it only has one output and I need more flexibility. The Evo Hiface will give me that. I have never seen the units and there is no local shop that demonstrates them. I will have to buy them blind.
Any comments would be greatly appreciated.
