Up was discussion about 040 or 060.
There is still in production Tekmos TK68020 cpu it is 68020 compatible 33mhz, build in fpu support also extra features (bigger ram support also virtual memory, cache, ).

This can be very cheap alternative too for Atari ST / EmuTOS computer. With 16mb ram and fpu and 33mhz can be good alternative for future too. There is Amiga 500 turbocard.

But also 040 can be interesting (lower price than 060) MAC spare parts...
