If at first you don't succeed, use YouTube and eBay!
There looks to be a feasible solution to the control precision issue which involves replacing the 5 DC motors with step motors and using a Raspberry Pi (which just happens to have been sitting in my cupboard since the summer) to control them.
Before getting too excited though I need to check I can actually get a step motor to fit within the robotic arm, they're currently £5.50 on eBay so it's worth a punt.

The theory at least is to replace the USB I/O PCB which came with the arm and use the Raspberry Pi instead to translate the movement commands pushed to it from the C# app on the PC. Michael Horne has created a project to control four step motors, albeit without PC input, in his blog.
