I have yet to see any Nesika, BAT or Stolle (Kelbley's) action depreciate in value. I agree with 86alaskan, a barrel blank and chambering is half the cost of an interchangeable barrel setup. You still end up with 2 bolts (if using different sized bolts such as standard and magnum). I'm pretty sure just a factory barrel replacement would still be more than a blank and chambering by a smith. I however, cannot attest to an MRAD's resale value.
