I'm the same way for the same reasons Jay, although I haven't heard of anyone getting robbed or fires or anything thank goodness, I always take pics of the builds I do (although I don't usually post pics), both for the buyer and for me. I find it helps if I can show potential customers what I've built in the past, its a good confidence booster for the customer knowing that I actually do know what I'm doing (most of the time..lol). It also lets me keep a record so if he/she calls a year later I can look back and remember what I built, helps with the oldtimers memory loss..lol.
I have been pretty lucky with my clientele and the high end builds but I do get my share of mid to low end as well, it all balances out in the end and frankly?...I just enjoy building the darn things
