You don’t have to buy it.
Preston 1399 clone brand new with more careful machining for $285 and selling out every production run.
Now in cast steel instead of bronze. You can also get the larger version.
That self-same-seller offered that Tyzack router for £1100 a while back….. it didn’t sell.
I recall that an identical tool, complete with the garish 1950’s box and all the cutters sold at the same site couple of years ago for around £600, which raised a few eye-brows at the time.
It was amazement at the prices such a simple tool could command.
