The ISF techs in our area aren't big fans of my company. I don't see a big benefit in spending $380 for them to calibrate a 42" - 50" plasma/LCD which is what's common these days. That's usually more than 10% (closer to 20 really) of the cost of the TV and I have yet to see any difference of value over using a good disk calibration system. Obviously they don't like this because I don't give them as many referals as my competitors do (except for the bigger dedicated theaters). Just to try it I paid for an ISF tech to calibrate a 50" Panasonic 50U series TV for a client. He spent a good amount of time on it and everything, but after he left the customer and I decided to switch everything back to factory and set it until it passed the eye test... I know I know, videophiles hate the eye test, but perception is reality isn't it?
All that being said, if you are droping $5K or more on a projector it's without question worth getting it ISF calibrated. I highly suggest it on all of our projector installs and will sometimes pay for it myself (basically including it in the bid at no charge) on a complete system project. It makes the projector look better and ultimately my business look better. I'm in full support of ISF on projectors and plasmas bigger then 50".
