I heard about this, but here is an endorsement straight from MSFT on what I've felt for a long time.
The telerik r.a.d. editor is the best editor you can get.
Per Mark Harrison's blog - you can now get the telerik r.a.d. editor FOR FREE with MOSS 2007. Incredible. How does CMS editing in safari on an apple backed by a Sharepoint 2007 server sound to ya? eh?
