Seeing as how I'm a complete knob when it comes to electronics, yes, I would like a convenient three pin header for a PWM cable. I'll probably be feeding two PWM outputs to two Victor 884s, so.

How hard is it to program the Arduino for this? Taking the joystick input, telling the Arduino what to do with it, then outputting it to PWM? If it's too difficult (keep in mind, I'm seriously not that good with electronics. I can assemble circuits but I couldn't tell you what they do, and basic HTML is probably the extent of my coding knowledge), I could just get the Vex Controller and also a Vex signal splitter. No programming required. A bit more expensive (well, close to three times as much actually).

If the Arduino is pretty simple to assemble and program for such a simple application, though, I'd rather use that.

so, CD, does the simplicity of the Vex system outweigh the cost of the Arduino? Especially for somebody as ham-fisted as me?
