I have the old GRS system- didn't see any point in upgrading to the new Q series and now they don't sell my old one. Regardless, it was the best investment I ever made for my bench. I started with just the basic set up, I already had the bench pin and mounting plate so added the original with the ring clamp, then added the inside ring holder system, then adjustable height bracket which you can set up to flip up or down, next added the swivel vise, then the small engravers ball, then this year the adjustable height slide. There is absolutely nothing other than forging I don't do using the GRS system. I'm probably one of their biggest fans
