Just curious, what makes this particular torque wrench so sexy? Looks pretty average to me. I have a couple of different brands quite similar. Now, a nice digital torque wrench would make me salivate.
Buy the best quality tool (not necessarily the most expensive) that you can afford. A good tool often makes the job far easier and less frustrating than "making do" with some cheap piece of junk (says the man with a Chinese bike lift that works fantastic). If you are doing a once in a lifetime project ... A - don't believe that ... once you do it once, you will probably do it again and B) if it really is a low probability, don't spend a fortune on a tool, get something just good enough unless you plan to sell the expensive tool later. When a specialty tool is called out, I have learned about 90% of the time, that tool really is necessary to maintain your sanity. Sometimes you can make a specialty tool. I have scores of weird tools - I had more before my Snap On Roll Away was rolled away by thieves. Which brings me to my next point - you never really own anything, even if you paid for it ... you are just the one that has it in your possession at the time. If you do invest a lot in tools, make sure your home owners insurance will cover them. When my Snap On box was stolen, I was young and a renter ... the renters insurance did not cover the $15k in tools that I lost. Where I live now ... for anyone to even find the place is a miracle ... so having anyone find the bodies after I shot and dismembered them would be just as challenging. As for a box ... having lost a really expensive box in my life, as long as I have some form of organization, a box is a box to me.
Last thing ... if there is a tool that you have always wanted ... figure out a way to get it ... if you wait, you will kick yourself for waiting so long. I changed tires on Oil Drums for far too many years before I bought my tire changer and there is nothing like turning a 15 minute fight into a 2 minute "pop" - especially when tires last 4k to 5k miles and I ride 25k+ a year.
