Those are the only ones that I know of at the moment. I have heard that some of them are being made in Korea, not just in China.
Recently while reading a review on Amazon, I think it was for a Piscifun reel, one of the guys mentioned the names of a couple companies that are making the majority of these reels, including major brand names. He's the one who mentioned Korea.
One of these days I want to go back and try to find that review and jot down the names of those companies so I can look into them further.
But, in my opinion, most people are paying way too much for their reels because they have a well-known brand name attached to them.
I flat out refuse to spend more than $70-$80 for a reel now. And will more than likely not spend more than $70 ever again, except maybe to test a reel so I can review it. Even for that, though, I cringe at the thought of dropping $150 and up for a reel.
