Need Advice on Equipment and Supply Needs

I would like to find an affordable 3D Printer like the Davinci 1.0 for $399 on Amazon, but I want to make sure it will do what I want. Also, I need to know what extra supplies I will need to get going. Here's what I want to make.
I'd like to make bobble head figures and just regular figures modeled after my friends and family members. So I need suggestions for what model of printer will do this, what extra software for scanning the objects or creating them from a pic if possible, and what materials and supplies I would need. Maybe some links to the good tutorials would help me.
Thanks!
