The PIC16F914-I/PT is a good price and it has a PLVD module which would save me $2. Just need to figure out how to use it

It also talks about a "Precision" internal Oscillator. Is this good enough for serial comunications in picbasic pro? That would save me another $0.50

Thanks for the tip on the Parametric search at microchip.

Generally not. Unless you can come up with a method to continuously recalibrate the internal clock everytime the temperature, voltage, humidity changes.
