Build it!
Used glue and pins. Tape and clamps.
Sandpaper, razor planes and fret saws.
Invent solutions to problems, customized and personalise the build.
But build.
come home from work, go to the workshop and let the real work begin.
More clue, more balsa and pins.
Loose track of time, miss holidays birthdays .... sun light.
But build.
And after 500 hours you come out holding a basic shaped model... and then the real work begins.
Finishing, detailing, refinishing redetailing and so on and so on.

Or you can just go to the shop and buy one finished.

Which one do you thing you're going to get the most satisfaction, the most rewards or the highest praise for?

You can build if from a kit, or scratch it from your own plans.
Doesn't realy bother me. Just don't assemble it and then say:
"I built it."
