The Shengshou Aurora is also a really great cube under $10. Or are we still talking only YJ cubes?
I do like the YuLong, though. Was really surprised at how good it is. But I don't ever use mine.
Edit:
Is anyone else gonna get the Moyu 7x7 Aofu? I'm really on the fence about it.
My shengshou mini is great, even though it locks up from time to time. I don't know if I can ever get used to a full sized 7x7 again.
