Now now ladies (and gents), let's be nice. It appears the OP is planning a special trip to NYC, so why not help someone out who wants something special to commemorate this trip?
Since you've had so many threads, I won't recommend anything in particular. BUT, I will say, why don't you look at some stores while you're there and shop around? Don't buy on the first visit to the store, but think about it before you leave, and then you can buy it before you leave! Good luck, and I hope you find something special that you like.
