I have been thinking about investing in a skull for home study. I have found a bunch of plastic skulls that are marketed as being for medical and dental students. I have also seen a bunch of real skulls (but a lot more expensive) being sold on eBay. Right now I am leaning towards one of the plastic skulls. Below is a link from eBay from a plastic one that I am looking at: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3806663838&category=31480 Does anyone have any input? Does anyone study anatomy at home with a plastic skull? Real one?
