The 680x0 range is a dead end, its too slow for modern applications and no-one would touch it. PPC is the way fwd.
It would be fine for 'new' Amigas 5-10 yrs old but times have moved on and it would be uneconomical to produce such machines like the Boxer and A5000 now.
The AmigaOne is the way to go, support it and buy one otherwise live in the past.
