From what I understand a Polar star is fairly easy to mod into it. That is assuming you don't mind looking like a ghost buster
As for the computer needed for the debounce.

$65 and I think he rapes canadians at $20 shipping. So an 85$ computer just to balance the debounce issue. Than you need to install a mosfet after that.
I wouldnt feel bad at that price tag if it was built into one of Xtreme Fires mosfet's, but being essentially an external 65$ part which should be built in. I refuse to buy the damned thing.
