I do buy some smaller items from the king such as batteries, esc', connectors etc but i know i am taking a gamble and may regret it later. I am willing to risk it for low cost items but the thought of buying a $400 - $600 complete rig from them and having to spend much more to make it some what reliable only to end up dealing with the shotty customer service ticks me off.
Been there, done that boys!
This is how the king gets you. They are hoping you wont save for a while longer to buy a quality rig. They know its hard for most of us to save and when we see something that "looks" cool we impulse buy. Do your research and think on it for a bit. We work too hard for our cash to just piss it away. Don't buy a copy-cat clone! Buy the original from the original and you will be happier in the end.
Good luck
