uhh..this may seem like a stupid ass post, but try to bear with me. i'm lookin to buy a torque wrench so i can start doin some stuff myself. mainly i'm lookin to get one for my lug nuts. is 3/8" drive fine? or is that too weak? also, what makes a decent torque wrench? is something like this decent, or a POS? http://r5.us.rmi.yahoo.com/rmi/http:...45487&ccsyn=15

any suggestions would be good. thanks!
