And, for those from a by-gone era and different skill set:

For Heavy-Lifting: K&E Log Log Duplex Deci-Trig (10-inch or handy 5-inch). Or, maybe, a Deci-Lon

If graphing is needed, go with a HP-50g (can be set for RPN or that other stuff ...).

For those who deal in "Dimensional Analysis" ... K&E Analon.
