thanks. Are you sure about those numbers? http://speedlights.net/wordpress/wp-content/uploads/2011/03/Man-Flash-Power-Index_04191.gif
I almost ran out and bought a used SB-900 after what you said..
Also, aren't IPS monitors sufficiently color calibrated? Dell makes good ones for around $300.. also I believe most Apple screens such as Ipad screens are IPS.
If you really want to be careful about colour, the minimum quality monitor you need is an NEC or LACIE. Apple and Dell displays won't cut it. If you are serious about colour, you get an Eizo. Each of those options will likely cost many times what your camera does, and even still needs to be calibrated with external hardware.
