Rumata-
Working with paper is more enjoyable than electronics but lugging around Pub. 229 wouldn't be so bad if I considered that, no, I'm probably not going to sail around the world so all volumes aren't needed. Only, at my latitudes of sailing, Vol 3 is necessary.
What has kept me from using 229 for stars with declinations over 29° is using the Hc and the Z formula and a calculator. Hc can be calculated using the simple Casio fx-300ES (about $10) in about 8 seconds. Z takes around 10 seconds. Whenever using those formulas and calculator a thought passes through my mind when looking at the device that, "one of these days when you're most needed you wont work".
