Get the blued one and spend the $80 odd on Duracoat from Findlay's. Beg, borrow or steal spray equipment and it's a piss easy process. Might even find some GC that will lash it on for you for box of beers.
I still give them a light wipe with oil over the coat but never seen even a speck of rust after loads of water, definitely holds up better than my last stainless Howa 1500.
