The only one that I've tried that was similar looking was a herbin gift set and the ball left something to be expected wrt smoothness
Yeah Kurt, I had one of those Herbin RB pens too. It seemed really cheap in feel and quality so I gave it away. I moved on to a Borghini RB that I got from Peartree a few years back (Like the Yafa brand). Supposedly they were the original brand/maker, and they rebranded them for Yafa. I lost one (grew legs in class), and the other wore out (the ball/head becomes scratchy, and no longer writes). I heard that this is the reason why Yafa sells the Monteverde Mega Ball pens with multiple sections/heads.
I have a Pelikan RB currently that uses standard carts. The head looks like this schmidt setup. So far, so good with it! I'm disappointed that these pens do not seem to hold up well with long term use. I really like the concept!
