Hi Donny,
First, replacing a broken spoke is not that difficult and time consuming. Truing a wheel is. Since you have only 1 broken spoke, I would say the difficult part would be shedding, and then replacing, the tire and tube. Depending on the location of the spoke, removing and inserting a new replacement should not be that difficult or time consuming and “I” would not hesitate to replace the broken spoke.
Also, with the wheel off the ground, I would ping all spokes with a screwdriver to hear any significant sound difference from adjacent spokes. A flat sound will indicate a loose or broken spoke and a number in this condition will give a good indication of the overall condition and value of the wheel.
When installing the new spoke, I usually tighten the new spoke to a ping just below the adjacent spokes within the same plane. This assumes the adjacent spokes ping close to the same level and closely relate to the overall ping level exhibited by the other spokes within the same plane.
Again, I would carefully consider the age and condition of your wheels in context of the level of enthusiasm with which you drive your car. This consideration should help you determine whether you replace or repair your broken wheels. The harder I drive the more I would personally want the confidence and security of new or professionally reconditioned wheels.
Hope this helps,
