I am not much of an investor, Bruce. I just like the Rangers. The RD-7 is priced reasonably. I have two RD-9s (old and new style) and one RD-6 old style. They are thicker than the Ontario RATs and priced close to the same. I like the 5160 steel, too. Just wait until you get that Scapper 6. Mine has replaced the Ranger as my favorite 6" knife. I prefer it to the Yard Guard even. The S6 may not be much to look at, but it sure feels good.
