lupodrv - custom driver, programmable | BudgetLightForum.com
it doesn't look like you can have threemode with this, but it's pretty damn neat to be able to program your own Nanjg driver just like you would a Taskled driver.
No idea on price, I'm guessing somewhere between a standard KD/DX Nanjg and an Lflex.
