I'm just going by what others have said, but the YEP is pretty good and is an exact clone of a MUCH more expensive ESC. You won't find another ESC that performs as well for anywhere near that price.
IMO, I would not get an eflight ESC, but that is just me. The one you linked to is about the average price of an ESC that size, but there is just something about it that I don't trust. It could be a great ESC, I just don't know. I know Castle Creations is a great ESC, but you get what you pay for there. IMO, I would do what I just did and bite the bullet and get the YEP. Yeah, you may have to wait a bit for it to get there, but from what I hear, you will have a great ESC. Remember, Westy is using a YEP on his Goblin and it's working quite well.
