I've generally had good luck with Hobby King. I have gotten a couple defective items from them but Iknew that would be a risk with the super-low price. I have heard that they can be difficult when you have problems or returns but I have never verified that myself.

Shipping cost has always been a down side with them unless you place large orders to make it more cost-effective. They have a US warehouse now though so some items can be shipped for alot less.

Imay order from Hobby King again in the future but the local hobby shop, Tower, Advantage, Central Hobbies, Aeroworks and others will always ber my first choice.
