Have read about this conversion, how worthwhile is it, is is basically just a cost saving modification?

The math makes no sense, if you add the cost of adapters you're losing money.
The adapters are reused each removal. Plug prices are closer to $7 now (Denso) and they come gapped. My mag-check dropped to 10RPM after changing the wires, plugs, and adapters.

Galin my experience is the same as yours. Too cheap not to replace them at each annual. No more time consuming plug cleaning and gaping. In 6 years of use with one Pmag and one slick I have not had any fouled plugs or any ignition related problems. The auto plug conversion along with the antisplat wheel bearing conversion are the two best things I ever did to my plane and reduce the inspection time considerably especially if you're paying someone to do it.
Are you running Slick or Bendix mags?
I disagree with the above, almost invariable the plug inserts come out with the plugs,
From the PMAG manual:
The instructions for installing inserts from Light Speed is different. You install the adapter first into the cylinder head, and torque to the specified value. Then you install the plug into the adapter and torque to a different specified value, which was 5 ft-lbs less.
The adapters do not come out of the engine when you remove the spark plugs. The adapters are machined from bronze and are not a life-limited component. Put them in once and forget about them.
