Just my personal opinion here, but I would not buy a DaVinci anything. they are closed source which means you are locked into their software, hardware and materials.
and from all the reports I have seen (granted, not that many) the scanner in the AiO is not very good.
I just finished building my Atlas 3D Scanner yesterday and have been playing around with it since - so far, I am pretty impressed with it's capabilities - especially considering the price point ($300 USD + enclosure kit).
just finished the first pass on an old cardinal figurine... not too bad for a "cheap kit". yes, there are some gaps in places the laser could not see, and a few stray points here and there, but I dont have an ideal location, or lighting set up yet... a couple more passes with the figurine at different angles and I should be able to get a nearly complete model.
