Honestly, I would buy two off ebay used. One digital and one beam.
Here's why. Beams stay accurate but are harder to use. Digital or click wrenches are easier to use. What I do is occasionally check my digitorque against my beam by setting the digitorque to a specified torque, I put a 12 point 5/8 socket on the digitorque set it to 60ft and stick the beam torque on and slowly pull and watch if the beam reads 60 when it clicks.
You will only ever get a ball park torque no matter how accurate your torque wrench. There are too many variables on the surface and bolts and washers. But you still need to use one.
Get something like this and a digital:
