I tried to find the Gecko motors but they make a lot of things so no luck.
I did note they seem to have premium prices.
The Trinamic Motor Control 5160 on a Silent Stepper Stick breakout board costs ?15-?20 less if you buy a pair. Should let you do the same thing and possibly more.
I know conventional wisdom is you pay for quality and cheap is crap but China works on high volume low margins. Having the largest domestic population in the world helps. As does having a massive export industry.
Times have changed. They may change again. For however long it lasts we're currently in a paradise of cheap but reliable with marvellous specs.
Ant?
