Ken, I would think that if you pulled the axle shafts and pressed (hammered) out the studs before taking them to the machine shop, it would be less expensive to machine the axles. I have done it before at work and it only takes one set up on a lathe to do both the OD and the center register on the axle. If a new set of axles is $400, and the shop rate is $75 or less, it should take a competent machinist less than 3 hours to do both axles ($225).

Now, that being said, if the old axles show signs of wear on the bearing surface or you are planning more power or better tires for traction, than a new stronger alloy axle might be a better choice...
