Another option that I have just tried (2 orders in the last month) is Himodel.com. I ordered a 2.4 ghz module and some receivers and got them within 5 days (calendar days) both times. They are located in Hong Kong and shipping under .5kg is $11 EMS. They also offer fedex and DHL as options. Their prices are a little higher than Hobbyking, but they have more things in stock that I want and they turn the order in under a day.
Regards,
Curtis
