Craftman
I think the best parts in this hobby are:
1 - you get to build them (agreed!);
2 - if you make a mistake, you can always reprint it;
3 - it's not so expensive as other hobbies;
4 - you get to join ZEALOT (YAY!!!) and share experiences;
5 - you get a lot of rewarding accomplishment, mainly with those "too difficult for me" models;
6 - if you want, you can always spend some time to learn how to do your own models, "old school" or "new school" way (whichever suits you the best).
This is THE hobby!
