If you can, go with the Craftsman. It's a good middle-of-the-road value, priced under S&K and Snap-On, but still very reliable and accurate. The click-type are often on sale for $70ish at Sears. Skip the cheepies if you can help it. If you need to go the harbor freight route, just know your results may be inconsitent and be prepared for some possible guesswork.
If you want to save some money, the beam-style torque wrenches are much less expensive than the click-style. A good one will be quite accurate. Most people (me included) prefer the click style because they're easier to use in that you don't have to watch a needle...so there's less of a chance to misinterpret the results.
I lived w/o a torque wrench for years. Once I got one I regretted not getting it sooner. Have fun!
