To throw out one that is not great, just so you know what to avoid -

I went real cheap with this one from Amazon and while it technically works, it's really not a pleasant experience. The little wire piece that you run the yarn through before it goes onto the actual winder part just doesn't stay put. It's collapsible and likes to collapse midway through all the time. Basically have to hold it in place with one hand and crank the thing with the other.

EDIT: Apparently it was my own silly user error! I did not realize how firmly I need to pull it out, until it clicks a second time to lock it in place. I retract my previous statement. That cheap winder works just fine in light of this new information!
