it actually doesn't save anything because the switch the rev B used is a 
On-On-On switch, which is even more rare and pricey than the 3PDT one! 
The reason i modded the rev C was because of price. I wanted a cheap and 
simple solution. Also the wiring is easier than using multiple pole 
switches. Fewer wires, smaller switches that can be closer together, 
easier to get, cost less. Seems like an obvious choice to me, but I 
guess not for everyone...
