Where can a get a wattmeter that is easy to read? This will be installed for an equipment. The client wants to know how much power the new equipment is using.

I would go with a low cost meter like an Emon Dmon meter. The model Pro-Con will display Volts, Amps, Watts and KWH.

For cord-connected loads, you might try Kill-a-Watt
