Anyone have any have suggestions for a hard case for my rifle?

My budget is about $100-$150. I’m looking for something that I can leave locked up at home, not have to worry about my gear getting damaged by the rain, dirt, snow, etc. and occasionally fly with.

I was thinking along the lines of getting something from SKB, Plano, BOYT or Pelican.

I think the Pelican line is pretty good but would be surprised if it fell within your budget.
