I have built a 2 kits for 2 different friends. When they asked how much i say you just pay what ever you think its worth because your my friend and i have nothing on the bench right now anyway.One gave me nothing but thanks and that was good enough. The other is a butcher and gave me a 1/4 side beef and that was good enough. So i guess it just depends on what kinda man the gentelman is. If i offer to build something for nothing and get paid $50 bucks thats more then i would have expected to get but i sure better get a thank you.
