Joe11,
You can read lots of POE reviews here:
http://www.visajourney.com/reviews/poereviews.phpOr, if there's a specific VJ member whose POE experience you're interested in, you can click on their name, go to the lower left of their profile, click on timeline, and read about their POE experience.
We had good luck at JFK... no crowd (that seems to depend on how many planes arrive from overseas at the same time as yours), friendly IO, got the temp EAD, etc...
Best wishes to you and your fiancee, and congratulations on overcoming the 221G!
Happy landings!
