Actually I do not generally find out that I can not get more of a part
until I come to order it.  I then have to look for new hardware and make
sure that it is supported.  I am having to rebuild these boxes with sid
packages as those are the only ones with the relevant support.  

While I can build my own debs (and have done so in the past) if I can 
avoid it I would much rather do so as it is one less thing to do.
