The download is almost for sure not okay and the sales are only okay if they are used original disks. AmigaOSXL/Amithlon died years ago.
You may consider MorphOS - all you need is a G4 Mac with Radeon gfx (Mac mini, Powermac G4 or some eMac) to freely testdrive it. If you don't know about MorphOS yet you may start with the five minute read "What is MorphOS at http://via.i-networx.de/wim.htm .
I tried Morphos and it is a bit daunting to a new user of the system. It looks great, but I couldn't work out how to install my ADF disks of various programs.
I think if you're a more expert user, you can do whatever you want, but for new users, I wish there was a guide in getting your Amiga software across for new users of Morphos and a compatibility guide, that would be fantastic to help out new users.
