Hard decision, I don't think the wide is on eBay as it isn't mass produced in the same way.
I asked the official seller and this is part of the reply " We have some wider angle lense module mobius camera on testing, USD69.99 per pieces, the camera with accessories, usb cable, velcro, mounting base and screwdriver."
Note the word testing. Guess that just means that there isn't thousands available to sell like the A lens and hence no eBay listing. Nb shouldn't out of eBay offers for business be 10% cheaper (no eBay fees).
Not sure what the screwdriver is for, presume the lens module is pre fitted.
Also wonder if I can power it from my Lukas camera's USB port? The Möbius manual asks for 1A but I guess that's for fast charging, I'd imagine it only draws a few hundred milliamps @ 5v for operation (can't find a proper tech spec to confirm, could always measure it myself before possibly destroying the Lukas by it trying to draw 1A).
Great comments in the thread
For dashcam use i'm leaning toward B lens, might be able to lossy dewarp on my PC if I needed to.
Hmmm.
Would be good to have two cameras with both lenses
