I use a TI-30X IIS most often. The five memories are enough to perform pretty much any routine nav calculation with ease. Occasionally, when the TI isn't handy, I use an Android app called "RealCalc Plus" in RPN mode. You can set the stack buffer to "unlimited", which is handy. Rarely, I use a Casio FX-260 solar. I have also written nav programs for a TI-83 plus and have used a TI-89 (with StarPilot installed). I use MS Excel to do calculations involving large numbers of variables and to do "what if..." scenarios.
All will get the job done, but I prefer the TI-30X IIS most. For me, it just seems to be the quickest way to get whatever answer I'm looking for at the moment.
