You can usually get a better deal by going direct to the manufacturer, rather than getting the same tool with somebody else's brand name on!
I don't know the U.S. makers well, but in the U.K. and Europe, the majority of torque wrenches (irrespective of brand) will be made by Torqueleader in the U.K, Rahsol in Germany (part of Gedore), or Norbar, also in the U.K.
Both Torqueleader and Rahsol make a huge range. All of them are good, and the top end are awesome. If you see guys in the British aerospace industry using those gorgeous torque screwdrivers with coloured anodised handles, they are Torqueleader, also the rugged dial type wrenches with enclosed mechanism's!
The Norbar stuff isn't as good, but it's perfectly serviceable, reasonably priced, and a far better bet than the far eastern stuff at similar money! I believe they are available at reasonable money in the U.S. so that would be my suggestion if you wanted new!
Personally, I wouldn't hesitate to buy used! The more specialised a tool is (and torque wrenches are getting specialised) the better deal you seem to get used. You can get them re calibrated easily, but I've bought loads used over the years and none have been far out. Certainly good enough for my requirements!
