Hello Dave
Glad you are upgrading! For this kind of serious investment make sure you look at the alternative and imo more advanced system: The Pegasos 2. Even thought the Amiga 1 is a nice board the Pegasos2 is much more advanced,cheaper,and has more features! The Amiga like Operating System MorphOS is way ahead of OS4 in development. You can get the G3 version of the Pegasos 2 for around $350! Look into it!
