I got one of these and though i gave it to a friend to wear for his art opening, I examined it and it wasn't bad. Someone who needs one in a pinch or a new entrant could do a lot worse.

Channelling my inner-JLib/Niven, I've worn one on occasion at dinner parties I've hosted. Originally as a joke, but people seemed to genuinely like it.
Certainly an honor to be associated with as elegant a style icon as David Niven!
Those are some of the best prices for ascots/cravats that I've seen, especially with the pound now being much weaker against the $. If the quality is halfway decent, they should be a helluva bargain. Bargains in ascots seem to be a rarity. With neckties they are ubiquitous: I recently bought three Kitons ties for less than $30 (tax included) apiece at the nearby Saks Off-5th. Wish I could get similar bargains in ascots!
