Hello guys,
long time no see. First of, glad to see that some old members are still active and in good health.
Now, my one and only multi-meter died, sure I could try to fix it but I would also like to get a new and better one.
Sorry if I should be posting this in "Product & Service Reviews" instead.
So, asides from Fluke and Amprobe (which I would recommend for professional heavy daily activities) not many brands have survived that last 20 years or so.
My question is: Between the UT191E and the UT139S (or even the UT139E) which one do you guys have and recommend (and if not too much trouble why)?
My main usage will be in mostly digital electronics, some analog stuff, also mostly in low power, but I want it to be good enough for me to find issues in cars and general house electrical stuff and appliances and such. I want an digital electronics multi-meter that also works well in the handyman's hands. I came to these 2 models because of the price and general features. I'm leaning to the UT191E (cheaper and sturdier), but the UT139S (look better, has some extra neat features that I will rarely need).

Thanks in advance!
