Tried the Matter & Form for a couple of weeks then returned it.
It's about the best laser scanner around but I just wasn't seeing the results I was hoping for and certainly couldn't justify keeping it at £450.
I just don't think they've got it right yet with the cheaper laser scanners.
You're right about the Einscan-S, it is a lot of cash and if I'm being honest, I probably don't use it enough to justify the cost but the performance is there when I do need to use it.
Possibly the best budget solution would be David Laserscanner with a 2nd hand DLP projector and cheap webcam. You should be able to put that sort of setup together for about £450 so about the same as the M&F but with far better results.
David isn't quite as automated and requires a bit of post scan work but the end results will be similar to the Einscan-S.
