I've seen two copies of K.R. Norman's translation of the Sutta Nipata for sale... one with footnotes, and one without. The one with footnotes is more expensive than the one without.
A question to anyone who has read the copy with footnotes.... How insightful or useful are the footnotes, and would they justify the additional expense.

"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
