I never had a problem with that shield - until I tried to use it. You pay less for more work (and more headaches, and more technical jargon, and so on). If that turns your crank, go for it. The adage always holds true: "You get what you pay for".
I'll put forward a challenge to you though. If you can explain the differences between that board and the Rogue Robotics rMP3 shield, I'll send you a free rMP3 shield. [Offer only valid for Sannin

P.S. I'll steer clear of the fact that they also use Arduino in their product name when it clearly isn't endorsed by the Arduino Team.
