The Topeak caught my eye. But I can buy TWO fairly nice 1/4" torque wrench sets for the cost of one Torqbar. And do more with it since the fully adjustable wrenches are typically 2.2 to 22 something Nm in range from reading the specs.
And cost wise even up my way in Canada where things are more than in the US I can get a pretty nice 1/4" set for $33 to $40 depending on choice. And even the expensive ones are only up around $50. Which again supports the idea of just buy the two different sizes and consider it a life long investment. With much care at all they will last your entire life and be able to get handed down to the next generation.
