I ordered from Hobbyking site only needed male ends, the 10 pack of the Nylon T connector Male plugs SKU: 606Bx10, $2.65. They also have pairs and female ends. It is a good deal if you don't need them in a hurry. Only thing I didn't care for was the shipping cost is three times the cost of the product. But still less then buying them in packs of two for almost $6.
