Many have lamented the fact that a standard Vixen (or SW etc) finder shoe won't fit a Tak focuser. I personally made a new plate for my FQR base that allowed it, but I was searching AliExpress recently, and found this:

I promptly ordered one, and it arrived just now.
To say the quality is REALLY nice is an understatement. The manufacturer obviously did their homework, and the finish matches a Tak FQR perfectly. The milling is REALLY nice and it is not a cheap cast aluminium piece like many of the shoes out there.
Note: the stop screw is NOT included - I added my own from an old left-over Tasco thumb screw
Here are a few pictures. I am going to order a few more!
