Ah yes, the box isn't for sale. 
The whole thing is available for about $US 52 from Digi-key. I paid a bit more in Australia, but I am used to that.
I am going to try to make up a parallel programming header board (as suggested on other web sites) so that (for a particular processor) you just press one board into place (onto all the breakout pins) and it correctly connects together all of the relevant pins. My photo above shows the ICSP connections which are complex enough, and the parallel connections are about twice as many. I'm thinking of using a small piece of board, some sockets and some wire-wrapping to connect them all. Should work OK. Then I can recover if I mis-program the fuses or something.
