Does anyone have any experience or recommendations for a high-resolution, 
table-top 3D scanner?

I am wanting to apply for a university equipment grant to get a scanner for 
my lab (and anyone else who might need to scan). This will be in 
collaboration with bio and archaeological and art researchers. These grants 
usually run about $40kUSD.

It seems the popular NextEngine scanner (~6000USD with all the extras) has 
a resolution of approx. 0.1-0.3mm. That would be fine for my stuff - method 
development and human-sized bones, but my bio colleagues deem that 
inadequate for their needs - mouse-sized bones. We can get high-res from 
microCT, but that takes forever - about a day per scan and the files are 
huge, e.g., >30GB.

Similarly, the Artec Spider (22,600USD) has a resolution of 0.1 mm. It 
promises some advantages of hand-held scanning, which would benefit my 
archaeological colleagues, but I am hearing from users it might not be so 
great in actual usage. Not sure if it supports a turntable/table-top 
operation option.

So, does anyone have any suggestions?
high-resolution
portable (might need to travel with it)
fast, easy table-top operation
<$40kUSD
