Since this is your first torque wrench I'd suggest strongly to getting a beam one for several reasons, taking away user error they are the most accurate. They never lose calibration as long as they are not bent, and they are stupid cheap.
Please resist getting a click type torque wrench because when they fail you won't know till you break something and they suck t everything else.
I personally have a few(different units) all the same style and brand which is a CDI dial torque wrench just because I like to see how much pressure is being applied to let off right at the right time.
Last but not least, please understand when a torque wrench says its range is 10 to 100 that you should not use it for the lower end because they are not as accurate in the lower range I think it is somewhere around 20 to 40% less accurate in those ranges. A good rule of thumb which I follow when I buy a torque wrench is I only take into consideration the top 50 percent on a torque wrench's range because under torquing or over torquing one bolt may mean complete failure and that isn't worth the risk to me with the work I do.
