Rich, I'd recently seen a link to just what you're looking for on one of the US-based forums. Not 100% certain but I think it was Hobbystore.
I'll try to find the URL proper. Hang on.............

Nope, no dice - sorry.
I'm pretty sure that it was indeed a Hobbystar advert, over @ rcuniverse -- you might try snooping around there?

As an aside, have you thought about rolling your own?
