Quite a few girls are using Sony EVID100 Cameras
http://usasecuritysystems.com/produc...y_evid100.html ususally about $1,100.
Sony have a new HD version now but at $3,500 I think many will wait for the price to drop and dont know of anyone using it yet.
Of course some use logitech $50 - $100 but when your trying to get up to 5.99 + a minute ,they just dont cut it.
Best site ? from all the data I have it would be cams.com ,but then again thats only my recommend.
Hope that helps.
