You might have a look at apt-clone, which does the same thing as the 
aptitude bundle, but with the added benefit of not using aptitude :). 
Also if you install dpkg-repack, apt-clone can use it to recreate 
packages that you installed manually if, for some reason, you no longer  
had access to them and weren't available for download anymore.
