Sorry I missed this thanks for your contribution. I'll likely be updating the OP this week as I've been focusing elsewhere.
Then there is the cheetah miner f7!
I'll keep an eye out but won't add it to the list until it ships and can be confirmed real. Apart from that you can start a discussion tread or find one if it exists and discuss there. Thanks
agreed with the method
ultimately i was posting to actually necro it for you and it was the only piece of genuine info i could offer so i am glad

I am not suggesting anything about Cheetah other than I know they exist as there's F5s out there
