Here is the link to tennisrecruiting's 2012 Spring Class rankings. http://tennisrecruiting.net/article.asp?id=1351
It's interesting to note that the ACC has 4 Top 10 rated classes while the SEC just has 1 (#7 Georgia).
The Ivy League has 2 top 20 classes.
Don't hang your hat on these rankings though. Recruiting for next season is far from over as many top teams will try to get guys for the spring season.
