The axles are pretty tricky for some reason. There's two different flange bolt circle diameters with two different patterns, and two different wheel speed sensor ring diameters as well. Some are straight tubes, some have a neck down section in the middle.
Your best bet is to look up the part number of the one that you need in RealOEM and use that to search, and yes some are only available new and run $400.

Have you considered a used one from a wrecking yard? They're pretty durable and if you can find one that the boots haven't failed on it should still be good. Piece of cake to regrease and replace the boots yourself, now you have a reman axle!

+1 for 'good used' even though getting them unbolted in the junkyard's a PITA.

Honestly, if a new halfshaft costs less than $300-400, don't use it. There is too much metallurgy in a good one to be able to sell it for $60, ergo the $60 version doesn't HAVE the right metallurgy, and will fail.

fwiw,

The ones less than that aren't usually new, they're remans.
