Also, I'm a vintage guy and while I have some newer calcs in my collection, I'm only looking at the pre-10BII models. What would you recommend and why? I'll second Thomas's recommendation for the 17BII, which is undoubtedly the highest-end Pioneer business model -- but is also easy (and inexpensive) to obtain, due to the large quantities manufactured in its heyday. It is the only Pioneer business model with RPN; it superseded the 17B, which was algebraic-only, after HP was supposedly deluged with complaints that none of their new business calculators for the late 1980s (10B, 14B, 17B, 18C, 19B) were RPN. The 17B and 17BII were the only Pioneer business models with the solver, or with the higher-resolution pixelated LCD. They were also the only Pioneer business models with the IR LED link to the optional thermal printer. John |
