Keyboards - Royal Kludge - https://www.amazon.com/dp/B08SWP5QPF/ and Kinesis Advantage 2 Contoured Ergonomic Programmable Keyboard - Dvorak version - like the top pic at https://www.fentek-ind.com/kinesis_advantage_2.html except the keys are labeled in Dvorak and secondarily in QWERTY.
Mice - USB Wired Mouse, Rainbow Lights Optical Corded Computer Mouse - https://www.amazon.com/gp/product/B0871RQ8XL/ - and a plain black corded Microsoft mouse with scroll wheel - Microsoft Basic Optical Mouse v2.0
TBH I'm not actually using the Dvorak keyboard anymore, I'm using the Royal Kludge and a plain black corded Dell keyboard.
