I sent an email yesterday but didn't hear back... I had called PA yesterday morning about a doser, but was told to leave a message and I never heard back. Anyhow, I'm still interested if there is any retailer that has one at 25% off.
Otherwise, I can always wait until the next sale... These things are slippery slopes and I'm a little concerned once I have the doser I'll be buying a new controller, etc etc...
