So thats what he looks like...I dont think I'll tell him he has sheetmetal underpants - looks like he goes to the gym...still as long as he is less than 6'3" I might be ok

I tried some experiments DAVID myself a while ago (like probably more a year ago I think)
I remember I emailed one of the bloggers that the handiman laser I used (since I found out on his blog that his company designed it) was a useless tool - which it was, sorry man- .the laser itself was good enough for my purposes though.

IMO DAVID was ok but not great. It would definitely help to get the best results to spend a little more on a fine line laser and a better webcam than I used..
I would consider this solution for some things but still go for a proper scanning service for important missions.

BTW DAVID 2.1 has just come out in the last few days
