$650 is a slap in the face, the pin is worth $700 alone and the mojo about 1000-1100. was the guy drunk? the only time i would ever low ball someone like that was if the snake seemed very sick and i knew it was going to cost me vet bills to get it health again, or I'm on canal st/jamica ave and I'm not spending $50 on something that cost $3 to make.
