I'm not sure if you guys have heard of Gadget Infinity but they have tons of great 3rd party photo gear. I read about them on Strobist. They literally have hundreds of items and it's like the Dollar Store for camera & radio gear. I ordered a set of $15 all metal extension tubes and a $13 coiled shutter release cable for my D700's and they arrived in about 1/2 the promised time via USPS (which was only $8). Products are well made and work as advertised - I highly recommend giving them a try.
