Bumpette...I've decided I might fancy one of these myself, but don't have any more info unfortunately, except that the top JET machines look related, and carbatec in oz appears to also source the same machinery.
I guess others probably know all about it but I've always wondered who these shadowy far-eastern companies are who make everyone's machines, well it seems Union-One are at least one of them. You can see rows of JET machines in their profile pics for instance...
