I wouldn't mind picking up a PSU if there is a true isolated one available..

Anyone find anything noteworthy?

oh, neat, cheap aluminum boards?. - more

this made me legit laugh: DUTCH GAIN

Aluminum switch toppers, 5 for $15.98, not bad

I highly recommend running anything through https://camelcamelcamel.com/ to ensure it actually is on sale before you buy.
