Just a data point in the disk-space argument. I've done some conversions of 
decent-sized CVS repositories and the Subversion repository did not use that 
much more disk space than CVS did. It ended up being about 1:1 SVN:CVS ratio 
in terms of disk space usage, maybe slightly higher but not a lot.

I manage to create a massively large Subversion repository (~10:1 size 
increase) when converting a CVS repository that had been pruned of old tags 
(cvs tag -d). The branches-without-tags confused cvs2svn and caused it to 
generate very many "unnamed" branches that chewed up a ton of disk space. 
Excluding those branches where the old tags had been removed fixed this 
problem.

I think the GCC folks and other groups who have very large CVS repositories 
(multi-gigabyte) have had similar results.
