Thanks for the invite John (and to Phil, nice work there).
The divider was originally made for my own use since my ability to count and use division plates turned out to be expensively poor.
I tidied up the code to make it more "friendly" and published the design on my webpage back in 2005.
Since then I've maintained it, fixing bugs people have discovered and adding a few extra features.
If you don't mind programming your own PIC's and can either make PCB's or are happy to breadboard it then all the files are available on my website so the cost is whatever you can obtain the parts for.
For those that don't want the hassle I offer pre-built units or simply the parts if you're happy to solder them up yourself.
If anyone has any questions feel free to ask.
