I would recommend this model. I am a kid and this took me about 2 to 3 hours with out any breaks. The guns are very fragile. It was definitely the biggest model I ever built. It was a vary complicated model. The decals won't come off so you need to soak them in hot water. You will need a big bowl. The decals are vary big. The inside is very complicated. I have very unsteady hand so I skipped panting the inside but i know it looks amazing. I am 12 years old and i say this model is worth the money. The only things you need is some good glue, a good knife and a vary good chair with good lumbar support. I really recommend this model. This is the best model i have ever had.
