The full CD image is over 400 MB for each, and about 200 MB for SQL Server Express and its accessories. I'm not big on these setup routines that download the bits and pieces while you're installing. Also, I'm not 100% sure what Microsoft classifies as having downloaded the app before the cut-off. If you download the setup only and then try to reinstall after the year is up, will they ask you to pay then? Quite possibly not if you already have a registration number, but I don't know for sure. Also, reinstalling will be quicker in future if there's nothing to download again. The downside is that if you download the CD image for all five languages (or four languages and one technology to be more precise) then much of what they contain will be redundant, like the MSDN library.
