So, I am in the market for a torque wrench and don't know terrible much about them. I really do not want to spend over $120 for one, so I have a few questions.

1. Would a limit of 150ft/lb's be enough for me, the ocassional DIY'er(I really dont/wont do anything major).
2. Clicker type or beam type? I was leaning toward clicking type.
3. Do the clicker type's have to be recalibrated? If so, how much would it costs, how often would I have to do it, and where?
4. How does this one look? I was eyeing this the last time I was at sears, and its on sale now. http://www.sears.com/sr/javasr/produ...orque+Wrenches

5. would having a 1/2 - 3/8 inch socket adapter effect the torque values?

Thank you in advance.
