Heh, I actually have three torque wrenches.
I started out with the 150ft/lbs one my grandpa left me. Solid, made in America Proto brand tools. Find one of those anymore. Typical 2' or so torque wrench.
However it didn't have enough capacity for the bearing nuts on my Ranger (225ft/lbs) so I went-a-searchin' and found a Husky Brand 0-250ft/lbs torque wrench at Home Depot. Lifetime replacement and about $75 if my memory serves me, but not overjoyed with it. I broke two of them on stuff that they shouldn't have had trouble with...but Home Depot replaced both with little questions. I still use it because well, it hasn't broke yet. I'm guessing 3' long.
Then there's the little Craftsman inch pound one my dad gave me. He bought it for working on his mountain bikes but never used it. He was going to get rid of it but offered it to me first. Damn it's handy. Lots of the little stuff that have important yet small torque values are too small for the Proto wrench but this does them perfectly. Not to mention I can fit it in a lot of places the bigger two can't go. Maybe a foot long.
