A huge (oh God, I can't believe I used that word) number of outstanding sonnets appeared in
14by14 from 2007 through 2011.
Here's a link to the archives. Most of the usual suspects are in there numerous times. Going through them are a bit of a pain, since they're chronological, not alphabetical, but if you develop a student or students who are sonnet nuts - and write in a modern voice - they might appreciate the lead. And looking at the archives reminds me that Rose Kelleher is another name to be considered.
