@ebm, I like SR's stuff.
At least the products I have tried. For the most part they do what they say they do.
YMMV, but I don't begrudge anyone who puts out a product, supports their products, warrants their products and makes money doing so.
In my experience, their fuses (especially the oranges and purples) are well worth the price of admission.
Time will tell on the new Master Fuse. I don't have any experience with that one.....yet. :)
