    The TI-30Xa is about as simple as it comes. You can directly enter in
    degrees, minutes and and seconds and convert to decimal degrees with two
    key strokes and vice versa. With three memories you can enter Lat, LHA
    and declination then calculate Hc in a seconds. Substitute Hc in one
    memory and you are good to go for azimuth. The solar version is
    considerably more painful IMHO.
