Upgrade option for Griffin 55M?

[Arct1k]

I have a new Griffin 55-M which is now discontinued - I think you last made them 10 years ago!

Is there any upgrade path for this ESC i.e. what would be the non-warranty repair replacement as I'm assuming you don't have these lying around.

Many thanks

PS You have to laugh but I did try to connect it to the Castlelink but not expectantly it didn't recognize it!
