Well the OP never said he was swapping pedals due to cost of a second set. Perhaps he just wants to use the same pedals on multiple bikes (for adjustment tension consistency or to save space in his apartment) or multiple pedals on the same bike (for variety)?
If the goal is to save money then, yeah, it would be best to simply get another pair of pedals, but if the goal is to be able to swap the pedals then a steel threaded insert would allow him to reliably continue to do so. But in this case I think I'd still recommend a quick release pedal made for frequent removal from Xpedo or MKS.
