Help me spend the airline's money on a new aidbag

The airlines lost my duffles coming in from overseas. I need a medium to large aidbag that ships RTFN. I am replacing a Utactic medium bag that was about $300 if I did the conversion right. Its about the same size as the Mystery Ranch RATS. I can argue for more because I'm headed out on a deployment right now and need an immediate replacement. Any recommendations would be appreciated. Help me spend the airline's money.
