A present for my father, best HP12C model?

[floppy]

HP12C? is whatever year a good thing. I got a new model in the hand and it has the HP key feeling.
But why 12C, why not HP15C? (HP15C is a bit more expensive)
If your father is working around the house (repairing), he will need few angular and sinus and cosinus calculation before he cut the wooden pieces. A scientific HP15C would be the "engineer" choice.
Calculating the status of his account on the Jersey Island (see Pandora papers; perhaps your name is there?), then the HP12C is probably a good thing. haha
