--- Quote ---Continuity speed is moderate (About 100ms).
Continuity beeps when resistance is below 30ohm, this is adjustable from 0 to 2000ohm
--- End quote ---
0.1sec...Should be fast enough.

That is really nowhere fast enough IMHO. Most Fluke meters, like the 87V, detect 1ms shorts (and transient open circuits!). This really is useful when swiping across a row of contacts to find the other end of a conductor, or to identify transient short or open circuits in a cable, for example.
J-R:
I don't think it was mentioned yet, but the Keithley 2110 (made by Picotest) can be found frequently for around $400. It is pretty well equipped feature-wise, has USB, a lot of pro-level features and boots instantly. Yes, the smallish display attracts some derision, but that helps to keep the the prices low when you're shopping on ebay!

I agree. 1ms is the 'required number'. Even at 1ms you still hear a 'click' so you know something is there.

anyway his budget is up to maybe 4-500 he wants this to last a long time and not have to buy one again for a good while (though imo once he catches the bug ill bet he ends up buying more like most of us) and he was offered a brand new hantek 3055 in the box for 400$ even which for that unit seems a good deal but they dont seem to have a great rep around here. sdg reviewed them and liked them.
but i also thought he should spend maybe 200 or less but he is set on something a bit higher end then that to last for a while and he is looking at 5.5 digits. i told him he really doesnt need more then 4.5 but he wants at least a 5.5 (he wanted a 6.5 till he saw those prices new lol). not really sure the hantek would be the best choice but then im not sure in that kind of budget what would be. that is his max for a bench meter though im sure if he found something as good for less he may go that way. but he does want a new one not second hand (im not sure why but he def wants something new)

Well, for that kind of money I would be looking at the offers from tge more known brands here:
Rigol DM3058E
https://www.rigolna.com/products/digital-multimeters/dm3000/
Siglent SDM3055.
https://siglentna.com/product/sdm3055/
As for the current discussion between old versus new, having an older high quality model gives you a lower cost ticket platform to experiment with different and interesting things such as GPIB and the minor and occasional repair. Not to mention that the availability of excellent service manuals which thoroughly explain the theory of operation of the equipment provides an unparalleled education route when compared to a more modern (and more integrated) model.
My progression was an old but incredibly accurate manual range Keithely 191 where the ADC is fully discrete, to a Racal Dana 5001 that has some microprocessing for the auto ranges, to a pair of 3478As that give me incredible accuracy when compared to the handhelds, at the expense of the convenience features of the newer models. Even still, I can easily test diodes on a 3478A, while capacitance, continuity frequency, etc. are done with more suitable equipment (including the handhelds)
So, the appeal and differences mentioned about a cheaper model such as the VC8141 become dilluted in face of an Aneng AN888S, for example, which has a much better display and the same convenience features.
Good luck in your decision!

Top-notch continuity functions are latching and will produce a beep long enough to hear. (If I understand it correctly, Fluke even does the reverse, extending a pause in the beeping to make audible a brief open circuit.)
