I am certain people have great luck with the hobby wing stuff. I've heard good and bad for all products no matter where they were made.  My experience was with zippy packs that almost burned my house down a few times and dead chargers etc.. from hobby king that didn't answer their phone while advertising their world class technical support.  The castle sct setup is 130 USD and with a tower coupon it goes down from there so the price difference isn't that significant considering the products are supported and I live right above the US.  I also prefer to reward the innovator and not the weasel who copies and takes the easy way out....where is the honour in doing that?
