TPS conversion options?

Just curious,
Since the TPS (ETC8495) is one of those parts that get's expensive to replace.... And I'll eventually run out the spare ones I hoard:

Has anybody installed this conversion kit?

I have not tried it yet but I have not read anything bad about it.
RN also carries a similar product... https://www.roversnorth.com/ProductDesc.aspx?code=PLM085&type=0&eq=&key=it
