You get what you pay for here.
A good case (definately needed for air travel) will start at $150 synthetic or aluminum
Perhaps a good used one for $100
This will be used for pretty much hauling guns in the truck. What would be a good one in the $150 range then. It is a present for my dad and he wants aluminum.
Take a look at the plastic/molded cases. The offer better protection giving more shock absorption. I have traveled with both for weight and protection prefer molded. The SKB models look nice and work great. Check ebay.
