These turn up on Gunbroker every once in a while. I have a 270, 280, and a 308. I've always wanted a 25-06, but haven't put one in the safe yet. When they have come up over the years for one reason or another I just haven't been able to pull the trigger yet (pun intended).
If I lived in one of the western states and had the opportunity to hunt antleope every year, seems to me this would be the pefect rig.
As I recall the good ones I've seen in the past brought around 800ish. But that could all be different now....
