ps - there is a caveat with Zeal submissions. You can easily get outranked by a paid Looksmart listing even if the title & description are lacking. the reason I believe is that with Looksmart submissions you can also specify keywords, in addition to the title and description. This can bump you up in the listings. So this is one area where certain sites could benefit more from a paid listing.
Though, MSN will sometimes not display the Overture listings, I am confident but not positive it's a monetary threshold.
To really get the most reliable traffic, use them all: Zeal, Ink, and pay MSN directly (they sell some spots at the top in house).
Free stuff I would think will always be subjugated in MSN by paid stuff, because they are looking for maximum SERP monetization.
Zeal members cannot do anything with commercial sites - only the Looksmart editors can handle them.
I have to agree with Jeremy. If you have a competitive search term, go with Overture and possibly Looksmart since you can specify keywords. If you are going for more obscure (but still lucrative) 2/3/4/5 word phrases - go with Ink. Zeal is good for the content pages.
