I just got a Cuda with the quad manifold for my birthday last week and just started looking for a foot pedal for it. I don't like the one made by them because it doesn't actually turn on/off, I don't like having to hold the pedal down.
I just read this thread and see Smutboy's not only turn on/off but are also on sale.
Now I need to figure out the size of the hose I have.
