Are you meaning M542's? If so they are very good drivers and rock solid, but again if budget is a problem, you need three of them, plus you need to integrate a break out or interface board. But with a gecko you get 4 drivers so you can add a rotary, and it has all the smarts and protection built in that you could want.
There are many other good ones out there like the Linistepeprs, etc, but the gecko is what i'm most familiar with and what I would buy without a moments hesitation. Anything but a good driver such as those types listed and recommended by others is simply throwing your money away.
cheers,

It's rumoured that everytime someone buys a TB6560 based board, an engineer cries!
