I have 2 of the TubeMPStudio's. I had a power supply fail on one (under warranty) so I just replaced it. I use one and the other is in a box waiting to be used. At 29.99, it seems to work just fine (I might have gotten the first one for less, but I can't recall).

I haven't really done any comparisons, but I needed something for phantom power so I got it. I now run the bass and roland spd-20 through it when I use those instruments.
