this amp caught my eye:

i understand it is a chinese amp, made by three stone, and goes for us$111 shipped. some of 3 stone's other minibox amps have a "ptos" switch, presumably to switch impedence between ety er4p and s iem's. this also has a "high/low" toggle it appears.
does anyone know what it sounds like, specifically with the er4p with the high impedence switch on? also, how can an american in seattle get one? i'm considering building a micro rig around it.
