Fred, If you're only going to do an assortment of through hole boards (this sounds like a light volume) then a foam fluxer is an inexpensive way to go. If you want to make the added expense of a spray fluxer then more information is needed about the flux that you plan to use. If you're going to use no clean, a sprayer with nitrogen works nicely. If you're using OA or Rosin flux, a foam fluxer w/o nitrogen will work fine. These are only general recommendations for a general question.

How important is spray fluxing versus foam fluxing, also how important is it that the unit have a hot air knife, and be nitrogen capable. We will only be using it for assorted thru hole components on mostly surface mount boards that have been already refolded. I don't anticipate doing any wave soldering of SMD components.
