Once again, found on Sourceforge. Although, it seems to have migrated off of SourceForge. Ah well, it's a good, free, NNTP client that is particularly good at binaries. For Windows. Supports downloading multiple files at once and using multiple connections at once. http://www.cosmicwolf.com/
I've been using Grabit from http://shemes.com for a while.
BNR2 is freeware. It looks good, I have yet to try it as my newsgroup binary tool. http://www.bnr2.org/
