I agree with the resonator, but for the applications that require the
accuracy of a crystal, what would be the practical solution? Of the
things you mention only the series resistor seems practical to me (the
average tinkerer will more likely stock a suitable range of resistors
than a suitable range of capacitors, and you can't lower the capacitors
below the PCB and other stray capacitance). So what would be a practical
value for a series resistor?
