Cartridge find Audio Technica AT155LC - any good?

I think that AT nomenclature is the most complex and inscrutable
while to make things even worst they added Signet and Precept
series there. I own the 155LC but have no idea where to place
in the ranking order of AT's. I got my from some Aussie in exchange
for some of my MM samples. I use only MC kinds so if I can make
some member happy I will do this gladly. 

Getting the correct phono preamp impedance is important to achieve flat frequency response.  Audio Technica specifies for AT-155LC a terminating impedance of 47,000 ohms.  However many phono preamps have an input impedance 50,000 ohms (like my Sony TA-1000ES preamp).  Combined with the capacitance of the cable and preamp and inductance of the cartridge's coils, this results in a GAIN of a few dB around 15kHz in the audio band (its the college RLC circuit calculation).  Some might consider this to be a sharper and clearer sound but in reality it's not FLAT response curve.

Hello,
I'm looking for a stylus for an AT 155 LC of which a recovery is available here https://www.hifi-classic.net/review/audio-technics-at155lc-298.html

I have seen opportunities here :
- https://www.lpgear.com/product/ATSAT0155LC.html
- https://www.turntableneedles.com/find5.asp?manfg=AUDIO-TECHNICA&modelname=AT155LC&Select=Mod...
- https://www.hifi-wiki.de/index.php/Audio_Technica_AT_155_LC
- https://www.dacapoaudio.com/1868-Audio-Technica-ATN-125-LC-styli.html

But prices for no reason... and how reliable is the news, if I believe some of the comments here:

If you have any suggestions, thanks in advance.
