I use the Eye1 Pro and Calman software. It was about a grand for the package. You can use less expensive meters and get into this for under five hundred. I use the Eye1 Pro because it will also do printer paper profiles and allow me to calibrate my monitor as well as the projector. If you do decide to take the plunge into video calibration, get comfortable. It's a fairly intence learning curve (but we are all 'tweekers' here, so you should be OK).
You'll also need a laptop, and a LOT of patience. That's why I say the $100 is well spent to have someone do this.
Now if you really want to go crazy, you buy an external video processor with CMS and calibrate the VP output per each source.
