:: So you have two different :: type of workbench, one for dealing with PIC/other ESR sensitive :: components, :: and another one for working on PSU for example? For myself no, but I used to work for a company that makes medical devices and ALL equipment in the tech lab was powered via isolation transformers. With an earthed wrist and heel strap (they couldn't get their heads around antistatic coats and shoes), occasionally touching a powered part would give a nice sharp nip. Still it was fun watching a heart pump speed up to 6500 rpm when this happened.
