Rex,
I think you already know the answer to this question, but I will explain to ya.
One is completly closed system.
It means it does not produce an open file format of the scan data. You are locked into using either 32-bit Lava 5 software, or a closed version of Dental Wings. Soon, it will work with a CLOSED version of exocad. Design Options are limited and you will be forced into yearly contract, or you get stuck with worthless piece of equip.
The other can be bought with 1, 2, 3, 5, and even 8mp cameras running OPEN 64-bit Steinbichler scanning software and coupled to exocad and also will work within exocad (by using exoSCAN software, or not) It produces open stl scan files. The other does not.
The interior is flat Black on mine to reduce noise data, the Jensen/3M version has bright interior surface.
There are no yearly fees with the One I bought. No stupid license transfer fees or such.
I see this as a MAJOR difference. No?
