Found these the other day, may be handy for anyone doing something they want GPS assisted. I'm considering the em-411 for the quadcopter's GPS assist (as its the only self contained unit).

• ET-318
• EB-3531
• EB-365
• ET-314
• EB-3631
• ET-662
• EM-411

Hints for buying from DX:

• The prices are including shipping!
• If you're getting lots of things, do it in smaller orders. DX get everything you order shipped to them, then package it all up and ship it to you. Smaller packages means you'll get some items far quicker.
• Dont browse, you'll end up spending about £900 if my experience is anything to go by :P
• Some of the stuff will be fake, or crappy, but its largely cheap enough you can forget about it.

Other Cool stuff

• Kapton
• 5x Laser Modules
• 10x 1W LEDs
• Component box
• 30W LED!!! (this is the unit i've bought for my projector mod)
