Well, instead of purchasing something, you can write your own CP/M 
emulator and put it in ROM.  It's an interesting experience.

When you say 'modern Z80' - that doesn't really make a difference.
CP/M specs state it should run on an 8080 - which means any Z80 should 
run the code.  The tricky part is creating a BIOS for your particular 
hardware environment.  Digital Research (who made CP/M) produced an 
'Alteration Guide' to help users with this process.

And I have a Gotek on one of my Osbornes.  Very convenient.  But I don't 
use them on all my machines.  I prefer to keep the drives running.
