When ever they become available again.
Also I would suggest the PAL system. It'll save you a lot of heart ache in the long run as the majority of good software is from across seas and can have screwed up timing like with music programs when running on an NTSC system.
Granted you can hold down your mice buttons and boot into PAL mode, but that's a pain in the arse.
Also some LCD Flat screens will not display the Amiga at all, such as my Sylvania here. It seems to be O.K. with my PAL Atari 130XE, but hates the Amiga.
