Ok, I went down to 1K and things seemed worse. So I went the other way and tried 2.2K with perfect results.

The part that sucks about this is that the breadboard and PCB and NOT going to have identical capacitance. I may not know what I'm talking about, but I know that much.

It sure is nice to see the circuit act as it should though. At least now I have an idea of where to look if things act up when I print this circuit. Some trial&error with resistors at worse, if I'm lucky I'll learn how to use an oscilloscope properly by then.
