Your choice for a Grendel barrel

[Rockdoc173]

I'm building my first Grendel and am conflicted on which barrel to go with. Since I lack experience in this area I'm hoping y'all can weigh in with helpful advice. I've considered every 6.5G barrel ever made it seems but right now I'm leaning toward either the Brownells (Satern) or Odin. I almost went Shilen but I'm not willing to pay $500+ for an AR barrel, this being a casual range toy. I'd like to top out at about $400, better still is $350 for the barrel only. Opinions need not be restricted to these barrels, however I really would like some input on them since, at the moment, they are the top choices. Here is my selection criteria:
•18" (20" possible if I really like it)
•1:8 twist
•SS
•Medium to heavy contour
•Preferrably headspaced bolt included, even if I have to pay extra
•Preferrably black in color but I can alway Cerakote it if necessary
•Preferrably fluted but, again, it's not totally necessary because my interest is simply cosmetic. I don't plan on subjecting this rifle to long spans of hodge-killin' sustained fire.

This is going to be a range toy, built for punching paper between 500 and 1K yards as my expertise builds. It doesn't have to be the toughest, meanest, fastest, battle rifle ever to come to fruition.

Thanks for the help
