Knitty.com has two springy top-down sweaters in their latest issue (or is it three sweaters?), so you might check those out, too. Pssstt . . . they're free!
Plus, here's one that I'm currently working on (which is on knitty.com, too, but I'm not sure if they've fixed the errata there, so linking it from Ravelry): http://www.ravelry.com/patterns/library/arleen
Good luck in your quest!
