fabulous Technics EPC-100 series re-tip

I'm pretty sure many of you guys own fabulous Technics MM EPC-100 (MM) in your rasenal, especially their top models like (P or C versions) MK3 and MK4.

The question is how to upgrade this cartridges with a new tip, cantilever, suspension:

-How can do the job properly and how much is it, how is the sound after upgrade compared to the original?

-How good is the motor of this cartridge?

-It's worth to invest more in new boron cantilever, new tip etc?

-No one can provide pressure fitted tip to the boron cantilever?

P.S. I know Axel can do the job, not sure if he can change the suspension, Soundsmith will not do that. VdH is not available in my area. Who else can treat that Technics MM right ?

Anyone on here did the same to their Technics EPC-100 mk3 or mk4 ?
@antslappy i assume you have tried all retippers in the world to say who's the best? If you chose Andy please read jpjones story above in this thread, maybe you will change your mind. 

BTW those SAS styli do have tension wire.
You’re right, my mistake. I took a picture of JICO SAS recently, before i sold it. This is the backside of the JICO’s replacement stylus assembly. Here is the structure of the jico sas from the manual. And this is a side the view of Jico SAS cantilever.

The original Technics looks way different than Jico. The side view of the original is completely different from jico.

But the Axel’s rebuilded Technics is another story. The backside of the replacement stylus assembly is way different from jico and from the original. The side view on cantilever is close to jico (same metal collar around the boron cantilever), probablly the same boron cantilever, but the diamond is bigger (higher). For some reason preffer Axel’s elliptical stylus compared to Jico SAS. Axel’s rebuilded version of replacement stylus it’s closer to the original sound of 205ED4 (mk4). The original i've recently sold, even with aged suspension, is much better than everything (jico sas or axel) !

Dear chakster, I missed somehow the picture by your contribution

from 09-14-2016. This picture shows the back side of the tube

in which tension wire is centered and tightened. You assumed

that the tension wire is removed but the little  ''tail'' at the end of

the tube IS the end of the tension wire. With this end or ''tail'' the

wire is tightened and after that glued to the tube end. What both

Axel and Andy try to do is further tightening of the ''tail''.

However tension wire is not the suspension we are talking about.

That is the rubber ring as by each other cart. I already explained

that removing and exchanging this rubber ring is not possible

without removal of the tesnison wire , magnet and cantilever.

But the real problem is to put all those parts back in the tube as

well tightend the tension wire thereafter.
