I bought a bunch of really cheap micro servos from them, just to see how they were. I think I got 6 servos for about $25 including shipping. They took about a month to get to me, but I wasn't in a hurry. I have been using them as throttle servos on my SPADs and they have been great.

Sorry, but I can't speak for their LiPo's. Hopefully someone else can help you.
Good luck
