Another all-round awesome computer for 68K and DOS would be a Quadra 630 DOS compatible - often derided for being a bit cheap, a mess internally and with poorly performing onboard video, but you can soup those puppies up with a full 40Mhz '040 (over clocked), big IDE hard disk, and an overdrive 486 (eg. DX4-100, over the crappy Cyrix 486SX25 they came with).

The Colour Classic is a versatile machine though, but to be honest only with the "Takky" modification.  I know purists won't like hearing that, however then you can run anything on it and fast.
