I had few, first one I build from some russian magazine, second I got was MUL3333 (bad quality), than I got Sencore LC103 and right now I dont have one
, however, I will be buying soon this meter as I think its the best one for repair business: Cap1B Capacitor Wizard
This is the only meter on the market that had all that ESR meter needs:
Voltage protection circuit
Range of up to 50ohm
Half of the range is for only up to 3 ohms which lets you accurately test large capacitors over 1000uF.
Analog meter for fast troubleshooting
Good quality - field tested
