Worth every penny
Excellent build, very high-quality bricks that fit well 99% of the time. Some of the technic parts were a little tight, but only 4 or 5 wiggly parts overall. Instructions are also excellent, although putting the drivers together proved to be very challenging for me; just takes very close attention. Finished product looks AMAZING, and an excellent reproduction of the Big Boy. Absolutely worth the money I paid for it, no question. This was my first encounter with non-Lego bricks and ill definitely buy from here again.
