3D scanner

Hi,

I would like to buy a 3D scanner for reverse-engineering purpose.

Creaform Goscan3D seems to correspond to what I need in terms of size and accuracy.

Object size less than 1 meter (with multiple scans) and resolution about 0.1mm.

So, is someone have experiment this or other 3D scanning  devices ?

Any other brand produce equivalent or less expensive product ?

This model (with scanning software) is about 25 k$ and it's the absolute maximum for me.

An other cheaper device would be appreciate.

Thanks
