I love buying cheap "chinese stuff".
As long as its got relativley good reviews and not any major obvious faults, im more than happy to buy stuff like that.
Nothing is like spending half the money than the guy next to you with the excact same kind of equipment except a lot more expensive, and both function just as good

Go for it! Just make sure you dont buy anything with bad reviews. Google the brand fex and check the general quality before you buy anything.

But hey, of course it is often a good idea to buy the more known brands like Futaba etc, because then you are often assured that it is good quality.
It is maybe a little risky business buying the cheap stuff, but I like it.
