I can't say I'm unhappy with the RAF but it really isn't a replacement for a miter gauge. In fact, even Incra says that. I'm able to use it and get consistent results but I am very wary of it flexing and treat it more like a piece of wood I'm sliding against the fence.
I would prefer to have a solid slider that doesn't use nylon screws to hold it tight to the fence. MRS might just do that. Dang, I seem to keep reaching for my wallet...
So, Bill, what did you have to do to mount the Mite-R-Slide? Pix?
By the way, does anyone else find JessEm's product naming a bit hokey? Mite-R-Slide vs MiterSlide, Mast-R-Lift Vs MasterLift
