That's not a bad price, but keep in mind if those axles need some freshening you could easily sink several hundred dollars in seals, bearings, brake parts, king pins, and that bent tie rod. If it needs freshening that requires more specialized labor, such as pinion bearings, that can really drive the price up if you can't/won't do the work yourself. I'm sure more than a few members on here can tell you about axles that after sinking time, labor and parts into them, they were getting close to the price of a nice built-to-spec Boyce or Dynatrac axle.
If it were me, since any axle I'd get I'd be freshening up anyway, I'd hold out for a better price, especially since you don't seem to have an urgent need. These aren't terribly hard to find, particularly if you are willing to travel or have them shipped. I can't really see paying more than a grand for a non-rebuilt set of axles. That might-as-well bug can bite pretty hard, though, lol.
