Holy moly! Two axis stepper motor controller for $67?! (You should check out the store connected with that site.) This reminds me I really need to finish my single-scanline CdS cell camera project...
Yeah it's a puny Arduino based one though. Look at the heat sinks. Don't waste your money - unless you really need the space the best ones are the ones that look like this:
Well, Leadshine is mostly acceptable (but not Chinese fake!).
Please sum all components (custom PCB, Trinamic controllers, arduino, connectors, enclosure, shipping components, assembling,...) add some taxes and you will get almost the same price.
It would depend on the amperage of the steppers involved, but sure - though I'm partial to the DRV8825 - it's considered a better driver in the 3d printer realm.
