Any help would be appreciated.
Thanks! 
fyi, creampuff looks like Eclat in sheep's clothing.

There's also Siena. Maybe too quirky.
Also, see Einhorn.
Which will always remain
mentally grouped with Eclat.

I have some familiarity with the work of the Eclat-lookalike font designer (one more edit is needed to get rid of all the places it showed up, by the way). I'd be a bit reluctant to accuse him of stealing Doyald's design, because I think they may both have used some old Art Deco -era books from the 20's and 30's as their inspiration. Many of the other fonts that Mr. N. C. has done have been digitizations of other authentic typefaces from that era. In fact that time period, as we know, seems to be in vogue again, and many foundries have revivals of old typefaces.
Stephen, does Doyald say that the Eclat design is his original creation?
Stephen, the showing of Eclat at Identifont says the design was 'Inspired by "fat face" designs of the early 19th century' (I wonder if they meant 20th?). In any case that implies to me that it is not completely original, and it's possible that the other designer may have used the same sources.
When going to purchase Eclat yesterday, I also came across the unmentionable font above suggested. As evidenced by this quote I came across, it was indeed based on Eclat :"Another phine phont phorwarded by Phil --- Letraset Eclat --- provided the inspiration for this addition to the collection. A mover, a shaker and a money-maker, ideal for when when you want to make a strong but elegant statement. The name? Eclat � �clair � Creampuff � seemed like a natural progression to me."
I downloaded it anyway for comparison and am glad I purchased Eclat, for two reasons (in addition to the piece of mind). Eclat has alternates - not many, but it's nice to have connecting and non-connecting versions of some letters like the lowercase g. Secondly the few letters that are different (lowercase r) I think are stronger in the original. No surprise there. If anyone's curious, I'd be glad to post a few comparison GIFs.
