so if you really want to try a different Amiga out this will be the time.
This is it

Back in the days I had only an A1200. Never owned a OCS/ECS machine. Now, my main Amiga is an A600. And I don't feel like I'm missing something (although I have an A1200 in the cleaning).
Still, if you do something that requires some speed, plain A500 or A600 will be slow.
