Here is a re-post from the PRO-BRO site for anyone else who is interested.

1 trip to Sportsman's Warehouse for a Plano Pistol case, $19, and a few minutes with a sharp knife get you this.
It's better than the $60 aluminum cases that the radio manufacturers want you to buy, but not as good as this $100 case http://www.pelican.com/cases_detail.php?Case=1450 I'd call it the cheap middle ground.
