I toyed with them at the local Woodcraft an number of times over the years. I couldn't cough up the cost, even though I have a lot of other Jessem, Woodpeckers, Incra, etc. tools. That's a lot of money for a limited use stock guide.
So, I tried the blatant knockoff Hongdui stock guides when they were about 1/3 the cost of the Jessem. I was very pleasantly surprised at the quality. Same one-direction angled in wheels, stainless, etc. I mounted them to a block of wood with Magswitches to sit on top of my Biesemeyer only when needed. IIRC, they were around $110 at the time while the Jessem was over $300
As an aside, I regularly use the Jessem router table/fence guides, more than all the finger-style ones I have. These things are the bomb!
