As coincidence would have it, I discovered we have a genie lift at work for changing light bulbs and such on the high ceilings- I don't get involved much in the routine maintanance and simply never knew it was there. But, we had a roof leak and one of the mechanics hauled it out to pop open cieling tiles and troubleshoot. Thankfully I was the one holding the drawings and wearing the tie and not wearing the harness- that base is awfully narrow for as high as the bucket goes; it must have been swaying 6" with just the exertion of popping off the drop ceiling tiles! Granted, this ceiling was about 10' higher than you'd ever see in a residence, but still, scaffolding is sounding nicer and nicer...
