He's a straight-shooter! I dropped my VX2100 from a height of about seven feet (tripod over my shoulder, cheap mounting plate). The case broke and the switch and something else was damaged. A new case would have been serious bucks! Mike discussed all the options with me and we decided to have him glue the case. Total cost was just under $400 for everything. It's been over a year now, the camera has had very heavy use and works as good as new.
I've bought three camcorders off of ebay, for a total of about sixteen hundred dollars. I'll sell you all three for $100. Do not buy a used camcorder that you can't hold in your hand and checkout thoroughly!
