I have just dealt again with Barry Gooley at Kokusai Kohki in Japan.

As before, it has been a very positive experience.
A few years ago, I bought one of their finderscopes as a special treat and have been very happy with it. All except for the mounting bracket which was a standard Vixen bracket that didn't perform very well. I've been designing my own, but checked back on their site to see that they now have a sleek black version of the finderscope with a purpose designed two ring, six-point mount.

Ain't that lovely. The finderscope mount by itself was too costly, relatively, so I weakened and ordered a new black finderscope package. It will look sweet on my scope!

Perhaps the one I am replacing will end up on the secondhand market or perhaps I will replace a GSO finder on another scope.
Barry is great to do business with - excellent and prompt personalised service! Being Japan, prices are what they are and the exchange rate doesn't ever seem to move dramatically in the AUD's favour.
But (risking falling foul of the TOR!

) check Kkohki and Barry out. He is very proud of his new alt-azi mount for scopes - the T-REX! 16Kg payload.
