Well JD if it all goes south then you can take it for the big upgrade for 16 big ones at Rabys/Ln engineering/flat 6. As a goodwill gesture I will kick in the first $ if it does not work....
Mind you you are not the first one to have it done but it probably feels like it to you.
You have my utmost sympathy as I watch your JD mobile go under the knife like a lamb to the slaughterhouse. In the meantime I put my trust in the IMS Guardian which is mere training wheels for the real thing. I am green with envy.
