Here is my list...over the years these tools havent failed me
Screwdrivers - Klein...period!
Meters - Fluke (Just don't want to bother trying another brand...)
Pipe wrenches - Rigid and Rothenberger
Manifolds - Series 41 YJ and Imperial 4 valves
Gauges - Digi-Cools and various analogues...I love my brass gauges and series 41 manifold for service work...
