I've received several offers from interested people before, and I've had to politely decline them. There are only two of these "bare" prototypes known to exist outside of the Gransee headquarters: I have one, and Chris M. in the UK has the other.
Yes I agree, that it would be valuable in a collection some day, but I still use mine now and again.
After all, it was meant to be tested and used, and that is exactly what I've done with mine. /ubbthreads/images/graemlins/grin.gif
I don't know what Chris M. has done with his, but suffice it to say it probably isn't right to ask, so I'd better let it go. /ubbthreads/images/graemlins/grinser2.gif
