I learned about the Wagner after it was discontinued, and eventually picked up on eBay. At first I had serious doubts, thinking for sure that I was overpaying. But there is no buyers remorse here - I love it. I'd be curious to hear how the knock-off performs. Twice as curious to hear about knock-off replacement cutters, as I only have the ones that came with the planer. They are durable, but nothing lasts forever.
