I was looking for complete rendition of Dikshitar's nottusvaras and I recently bought this CD - Vismaya (http://www.kanniks.com/vismaya_page.htm).
I am not qualified to review the music, but its definitely a novel attempt and a very good listen. Just wanted to give exposure to this CD if no one has heard of it.
Its not "pure" carnatic music, but has western/celtic blend. The voice of the singer is very pleasing.
