Ah you missed a white one on eBay fairly recently. I will keep my eyes peeled for you. There might be one on the Vigier forum for sale but I haven't asked weather it had sold.
I also have a fretless, series III, but I am finding I hardly play it any more, despite it being probably my main recording bas for a while. Like you I think the magic lies in the full graphite necks, mainly because I like the dead straight profile.
Cheers
