HobbyKing has several folding props.
I live in Lacey WA and get my orders in about 2-3 days.
I have almost always had good luck with them. Just make positive what you are ordering is from the US warehouse ( in Lakewood WA ) and in stock at the time you order.
I know many people badmouth HK, but without them my flying would be very limited.
I am totally happy with what I have received.
