These go for anywhere from $47.42 to $86. I could see getting one under $50 (ebay), but if it is going to cost a lot more than that I think there are better choices, like the Becker BK16 ($68) that has an excellent reputation as a field knife.
However, I do get that the Strongarm is a neat package with the locking sheath and all that. Gerber is more of a company making attractive consumer products rather than designs built for their usefulness, but the Strongarm might be a step in the right direction. It really depends on whether the blade has a useful grind or is too thick. Schrade has a few knives in this class, as does SOG.
For less "tactical" offerings, look to Scandinavian brands like Enzo, Ahti, Marttinni, Helle, etc for super functional knives are reasonable prices.
