I have all three models and a few other financial ones, and so far I saw just two other HP19B users around here (one, in fact, with an HP18C). The HP12C indeed has the fastest way to get to the TVM interface because it has TVM-dedicated keys. It happens the same with all previous HP financial calculators. I have an HP37E and one HP38C, and I have once used an HP22 and one HP27. All of these are predecessors of the HP12C, and they all have TVM-dedicated keys. Some models that came after the HP12C offered the menu option, and also lots more memory and extra resources. I prefer using any HP17B/19B to compute cash flow because they are faster when computing IRR and offer some extra features, like NFV (Net Future Value). Appart of that, the menu-driven softkey-based TVM is a different approach, these models actually do not have TVM-dedicated keys. Anyway, I see no trouble in that, and the extra functionality worth the lack of such dedicated keys.
I'd keep the HP12C (I also have Platinum and Prestige units) and, if possible, would give these new units a try...
