Cases for .50s

I saw an ad in VHP magazine for SKB's new .50-cal case, model ATA 50, so I had to look up the price.  Ouch.  $450 is a lot of money for a large piece of plastic.  Pelican's large case, model 1770, is similarly priced.  For that much, the Americase Aluma-Trans aluminum-shell case, model AT-50CalW, seems like a better buy.
