My Singer 401 Slant-O-Matic is as computerized as I'm going to get for a while. Also my 2662. My neighbors husband used to be a roofer and has one of those large magnetic roller. She runs that through her sewing room and picks up broken needles every once in a while. She has a wand magnet that she scans across herself to catch any that may have flown and landed on her. She found many in her hair over the years and in her skin. She's able to get to them immediately.
