I totally agree you really need to know what your getting yourself into
2 china products that are very good one is this digital LCR and another is this signal generator http://www.ebay.com/itm/221508521898?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
has a very good square wave Rise and fall time of ≤100ns perfect for amplifier testing without adding rc filter to slow it down and music is much slower then 100ns but its a good test plus this unit has real good bandwidth for audio testing/sweeping. IMO EXCELLENT
Did you mean to post a link to a digital LCR?
Look for XJW01 LCR meter on Amazon, eBay and Aliexpress. This model seems to be discontinued.
On Aliexpress they are available at around $100 but assembly is UNFINISHED, as stated in listings. I don't know what is missing.
This LCR was a "KIT" the main board was stuffed and soldered but you have to put it all together and make some cabling
Yes there maybe a new model that will/can test at 100kc but for what we do this unit is works fine. IMO every experimenter should have one just for matching R's L's C's plus so much more
Serious SET hobbyist needs LCR meter that can measure inductance of the OPT at variable frequency from 20Hz-20KHz. Any LCR meter that is fixed to measure at 100Hz/1KHz/10KHz; etc. points are not very useful IMO.
Also, variable Voltage signal of about 20Vrms and selectable Vsource of 30/ 50 /600 /1K ohms.

Certainly exists yet too expensive for hobby use.
Generator, resistor and true RMS voltmeter is enough for this purpose.The rest is simple calc job.
