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:

100 times better and they're not even any more expensive - $31 on aliexpress.

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.

Wouldn't something like this be sufficient in many cases? https://www.pololu.com/product/1182

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.

Only for the tiniest of steppers. So basically no.

In my experience you can judge a stepper driver by the size of its heat sink.
