if you have a harbor freight close by, $29 alum case full of foam http://www.harborfreight.com/18-in-x...9318-8538.html

it's actually decent quality. hinges are good, handle is good, latches are working good still I can't complain. been using it for 2 years straight.
the dividers will not stay in place all that well. but I put shoe goo on them and they don't come loose anymore even with 3 4s batteries hitting against them.
