I got the premium edition for 50% off, that's good enough for me. And they shipped from Germany, not Italy, so it arrived the next day and not weeks later.
The download you get immediately after purchasing however is no longer an ISO image but a Windows installer, so you have to install on Windows first in order to get access to the Amiga files (or wait for the DVDs to arrive).
AF contains ADF files up to WB 3.1. And it contains something they call 3.X preinstalled. There is no installation material for 3.5 and above, but I think you could use the files from 3.X on a real Amiga if you remove the UAE-specific programs.
