Has anyone used Proto Design Labs internal decoders for Kato #6 or #4 n-scale Unitrack turnouts? While looking for turnout decoders, I came across a PDL video on installing their internal turnout decoder. It appears to be pretty straight forward: only manipulating screws, nuts, unsolder/solder two wires, inserting decoder, clipping/trimming some, testing and assigning an address. The PDL decoders look like a decent product.
