That actually the High Voltage version. You can tell by the shrouded stem. The High Voltage models usually cost extra because of extra insulation and high voltage rating. You can probably find similar "regular voltage" version and it will be less expansive.
I found Cementex kit in a pawn shop. Mine are also high voltage version. The screw drives in mine are probably Kline Tools, but there is no marks that I can see or they are covered by the protective high voltage coating. Some of the tools in the kit are marked with Channellock logo so clearly Cementex buys tools from others, applies their high voltage protective coating and sells them under their brand name.
