Congrats! Live changing event that is.
Dunno what "conventional" is in your neck, but here, we bought every newspaper of the day and the following day, and presented them when the kid became 21.
As to basses, I'll only mention that 2013 probably will see the lim.ed. 10th anniversary Bongo.
Yes, it's expensive, and maybe a nice gift like that should be about typical 2013 style and choice of colour rather than about an expensive bass.
best,
