i enjoy building because i know every piece of wood that goes into a model. if i see something i don't like, i change it. i find it easier to come up with $10 here and $30 there compared to $400 all at once. i also get the satisfaction of somthing i make with my two hands taking to the sky and returning to earth. i also like the fact that i've learned more tips, techniques, and skills than i ever though i'd learn by building. i'm not flaming on ARF's i own a few myself. however, i don't think as dearly of them as i do my kits.
