Even though I don't agree with the price, I'll have to agree with AMB, he's the designer and he should negociate with Ken the terms.
However I will love to read the reviews of this amp when compared to a DIY mini3 from mister x or rockhopper!
ps: AMB, I don't think that the price includes a LOD, Ken will have packages, but the 285 is for the amp, 9v battery and a charger.
