Dealers...

here's a quick list of stores to search for parts and to buy the little quads!!
(many more to be added!!!!)

(China - ships wordwide)
Banggood.com
Gearbest.com
Tmart.com
DX.com
Hobbyking.com  (has warehouses in multiple countries)
(USA)
Newegg.com
bhphotovideo.com


RC groups forums as a latest deals section.. pretty good break down of parts and where to find as well as some pricing (which I'm guessing isn't auto updated? but still decent for basic research!!)
