I agree that the SunPro 7678 is a nice combination, but it has one (IMHO)
serious flaw: DC amperage. It only has a 15A setting, which does not
work if you need lower sensitivity (e.g. 10mA for fuel injection pressure
If you don't need this, then it is a nice unit. For low amp readings, I
borrow my friends Radio Shack top-of-the-line unit that even includes
capacitance measurement and BJT transistor tester. I think his cost a bit
over $100 while my SunPro came in at $90 from Autozone. One of these days
I'll spend the money on a reasonable Fluke...
