i tracked down 2 project boxes at a small town radio shack here in Colorado... had to drive an hour to pick them up but they are getting scarce.
I did some calling and found this store that had 2, apparently the only 2 they had ever ordered, and i got them for pretty cheap. Radio Shack did tell me that the project boxes have not been made for a long time and most stores have had no stock of them for several months. They said once they sell out they will be out and did not expect any new ones to be made for the short term. Radio Shack does not have a supplier at the current time so they are not making new project boxes, or any other Shack designed items for that matter.
