If you feel you need a torque wrench, you should only get a good one, otherwise tightening by "feel" will serve just as well.
Trying to get a "wide range" instrument also defeats the purpose. The wider the range, the less accurate it will be at any point in that range.
Stay away from "deflection" type wrenches, especially when measuring inch lbs. They are notoriously inaccurate right out of the box.
The best will be dial or digital, though there are some "decent" click types that should last forever without recalibration, with no more use than a hobbyist will put them to.
For our application where we are tightening screws, I'd recommend a torque driver, not a "wrench".
Good torque wrenches are precision calibrated tools, the same as your micrometers. They can be pretty easily knocked out of calibration so be careful with them. I wouldn't borrow one from a neighbor or buy one from a pawn shop.
I have a couple of Precision Instruments drivers that I'm happy with. These aren't cheap, I think I paid about $150 apiece (there are more expensive), but these are pretty good and hold their accuracy (2%) pretty well.
I have a 0-24in.lb. that measures in 8oz increments and a 0-75 in. lb. in 1lb increments.
Having gone through that long spiel, I also know a lot of guys that torque by "feel" and their guns don't seem to suffer from it at all, soooo...
