I don't know about the Thylacine in the A3000, but in the A4000D and T, the Thylacine works fine; it ain't the fastest USB solution in the Amiga arena, but it is available and newly made -- can't say that about any of the others, although I'm sure the USB module for the X-Surf 100 will be available within the next few years, just like the ScanJuggler.
