I used to have a cheapo one from TireRack but I lost one of the screws that hold the spring assembly to the head and there is some play so I question whether it's still accurate.
I replaced it with a Sears craftsman 1/2" torque wrench, which I believe was about $79. I'm quite happy with it and use it for all sorts of stuff on the car. I think it goes to 150 ft-lbs.
The only problem is that it's not very good below 25 ft-lbs (not a surprise). I just used it for SS brake lines on my car to tighten the brake line banjo(?) bolts, which should be 24ft-lbs. I set it to 24 and proceeded to over-torque and snap the head off one of the bolts. Backed it down to 20 ft-lbs and it worked fine on a replacement bolt.
I echo what G19Tony said: get an inch-lb torque wrench too for things that don't have to be that tight!
