Whats so great about A882 drivers, Iv seen a number of people recommend them.
Do they offer any great benefits over something like this,

Both are capable of handling 80V and more current than my motors can cope with.

The only difference I can see is stall detection. Is that really worth £20 per axis, £80 for all 4?
Any suggestions where to buy a toroidal PSU? Id rather not make on.

The only PC I have are laptops, so no serial ports unfortunately. Which means i either need to buy a PC or an expensive usb or ethernet controller. Hence why i was hoping an arduino might do the job.
