I suspect you need the entire electronics package and not just a breakout board
traditionally breakout boards just enable you to connect a PC printer port to your stepper motor drivers
Are you looking for an all in one breakout board and 4 axis stepper drivers ?
At one end of the spectrum you have cheap chinese boards using TB6560 stepper IC's that may not last very long
Running off a 24V DC power supply your not going to step the motors very quickly

At the other end you have the Geckodrive G540 or the newer Leadshine MX4660
using a 48V supply for the G540 or 60V supply for the MX4660 will be an advantage
The other question is what spindle motor are you going to use ?
A 3 phase spindle motor with a VFD drive or small DC motor with a PWM speed controller ?
How many mains outlets do you need to be CNC controlled - eg for vacuum dust extractor
If you want to use a USB or ethernet connection instead of PC parallel printer port
use an original version of a motion controller like Warp9 tech designs smooth stepper (EES) or cncdrives UC300
With hacked chinese copies can find your on your with own with little or no support
