I was "this" close to snaging an Apollo 630 card for 4-500 euro couple of weeks ago 
The Apollo 630 is still better. Happy me, i have one (40 MHz full 030/68882/32 MB of RAM) :-)
A nice improvement would be the compatibility with the Indivision ECS, that the Apollo lacks.
There is also the 2 problems of the Apollo: dangerous position over the 68000 chip and heat inside the tiny A600.
