I haven't built and painted a model since 1991.
I am too lazy now and would have to use reading glasses or a magnifier to paint the small parts and plus the time to do it. That is why I turned to die-cast and pre-built stuff. Just as cheap too by the time you buy the paint and model, it probably would cost more anyway. Though, there are some really great models that there will be no way any die-cast companies would make too.
