Has Roy agreed a price yet?
He was selling them for $48 including PSU but that was before the dollar lost half of it's value.

ChaosLord is right, these Averlogic 16-bit scandoubler combinations will "clip" AGA colour from 8:8:8 to 5:6:5, but so do half of the existing Amiga scandoublers. There are very few AGA / 24-bit scandoublers.
As for RGB being analog, you are correct, but it is converted back to digital before scandoubling and then back again, another lossy part of the process inherent with all external scandoublers.
