For the 40 ft-lb up you can find a lot of options. For the smaller torques, I would say the KD beam up to 90 in-lb and Avery (CDI) 20-250 in-lb click type recommended are very high value tools. I studied this years ago and got the same tools. I got a used Snap-on rather than the avery, but for the price, I really should have gotten the Avery. The click type will allow you to torque in awkward places where you can not see the beam needle. The beam may be used where the click is in the low regions and less accurate.
You might find a snap on dial type in the 20-250 range on ebay for under $100 and that would be a good deal too, if it looks new. They are hard to catch.
Good luck, and happy building. A set of good quality tools can easily be resold with a high % recovery if that unfortunate need arises.
