Blast, if you only knew

... my calculator collection was never intentional, I just kept buying new ones.
kc2ixe, I guess it depends on what your needs are. These days, the calculator I use most is a simple 12C since I need a scientific calculator less and less these days. If you need the functions of the 48 series then look at the HP-49 series of calculators, if you just need a scientific calculator and could care less about graphing... then get a HP-35s... look like the original 35's but with current electronics.
