I seen an old ad for these on another board, I had to have one!
There's none on the bay UK so got this beautiful example from a seller in Sugar Grove, Illinois.
I wanted one with keys and all the accessories, as a lot of them advertised are missing the keys or a few bits and bobs.
I was rather apprehensive about the shipment, being its from half-way around the world, but the seller did a sterling job - purchased 9th July, delivered 19th July.
US $19.95 & $33.10 shipping. (about £32 UK all in).
Well pleased!
