Mionix Naos alternatives?

Hey folks

I've been using a Mionix Naos 7000 for a few years. Dare I say it'd the perfect shape for my wide hand. I tend to hold the mouse in a palm grip, and the 'bump' on the right side of the mouse keeps my pinky from dragging on the mat. I love this. My pinky dragging tends to happen with any other shape mouse. It seems the wheel is starting to break. It intermittently doesn't respond, or tends to roll in the wrong direction unless I roll pretty hard. Anyway, it seems the Naos 7000 may have been discontinued? It's out of stock everywhere, and the few places I've found that have them are pretty sketchy. (Third party sellers that actually ship a different model or mis-ship it, have been my experience.) Any recommendations based on my love for the shape of the Naos? My own research hasn't gone anywhere. Thanks!
