How much are you going to be using a torque wrench? The wrench you linked to should be a good usable range for bicycles, it just won't cover the higher torque parts(BBs and Cranks). You may be able to get away with beam style torque wrenches - you can get two of those for less than the Shimano and those 2 would cover everything on the bike. I think for occasional use, beam wrenches work just fine - I own a Craftsman high end and the Parktool TW1 low end. I also have the Effetto Mariposa Giustaforza clicker, which is an outstanding torque wrench - range from 2-16Nm, much easier to use than any other clicker, good positive feel with distinct click, and it's way smaller than anything out there(perfect for tight spots on a bicycle) - I could go on and on about the Giustaforza, I love mine. Might want to look into that one.
