I recommend the Casio fx-260 solar. No batteries, standard "scientific calculator" capabilities (in other words, trig functions, logs, etc.), very cheap, and above all widely available. It also happens to be water resistant. I've dunked a few in saltwater to see how they recover. In fact, they float fairly well at first, but even when they sink, after drying out they work just fine. I have yet to see one of these calculators fail.
The fx-260 is the required calculator for my Modern Celestial class. I'm teaching this class twice this fall at the Treworgy Planetarium at Mystic Seaport Museum in Mystic, Connecticut: the weekend of October 1-2 and also November 5-6. In between, October 22-23 I'm teaching my Celestial 19th Century Methods class (no calculator required for that one). Details at ReedNavigation.com. There will be an off-schedule short verion of my lunars class on Monday, October 24.
