I got slowest 533 mhz sam and my only complaints is that it could be faster. Otherwise the hardware seems high quality and rock solid stability wise.
The system itself also boots very quick and feels very responsive, but is not powerful enough for full speed UAE emulation and mpeg4 playback. It also still feels sluggish when using OWB or Timberwolf, but that i expect to change once they optimize the rendering engine.
