Measuring microamps

"What sort or rubbish meters have you been using? Most analogue meters I have used have had 100K input impedance." What sort of rubbish -current- meters have you been using? In context, I was talking about the current meter in the circuit referred to in the first post. Most analog -current- meters I've used have had around 1k (not K) input impedance. Nice little transistor tester.
