I was in the same boat a couple of years ago.  I wanted to have a good
engineering slide rule as both a conversation piece and as something to
use if I was away from power and didn't have my calculator.  Based on
the research that I did, a Log Log Duplex Decitrig is what you want. I
was able to get a couple of them on E-bay for less than $20 each.  I got
a K&E N4081-3 which is very nice and clean, and a Pickett N1010-ES
Trig. which is aluminum and feels less 'warm' than the K&E.  I also found
an instruction manual online for the K&E that will work for any similar
slide rule.  They are fun.

Take Care,
Lloyd Pack, P.E.
