I just picked up this Plano at Wal-Mart for $68.99.I carry my Condor SS in it. Love this case. But for Cabela's, here is one that should work for the MRod. http://www.cabelas.com/product/Shooting/Gun-Storage/Gun-Cases%7C/pc/104792580/c/104730480/sc/104368680/Plano174-Protector-Double-Gun-Case/709904.uts?destination=%2Fcatalog%2Fbrowse%2Fgun-cases%2Fplano%2F_%2FN-1100211%2B1000004310%2B4294734117%2FNe-1000004310%2FNs-CATEGORY_SEQ_104368680%3FWTz_l%3DSBC%253BMMcat104792580%253Bcat104730480%26WTz_st%3DGuidedNav%26WTz_stype%3DGNU&WTz_l=SBC%3BMMcat104792580%3Bcat104730480%3Bcat104368680
The particular one I got at Wal-Mart for $68.99 lists on Amazon.com for $121.21.Excellent buy at Wal-Mart's regular price. They don't list it online so it's an in-store special item only.
A "cheapo" rifle case will work 99% of the time. But if you're planning on doing any air travel you'll need a really good quality case that is lockable if you want to protect your rifle & expect the case to actually survive baggage handlers.
