Yes, I have etched holes in the pads. I am very happy with my Proxxon tools and also buy from DrillBitCity/drillcity (the Harbor Freight carbide bits are OK too). The camera you mentioned looks nice. I was considering a camera setup, but the UART interface COMedia C328R that I had was just too cranky to use. The hole illumination from the bottom is not a perfect solution, but it has improved my drilling skills.
