I use a X-Rite i1Display Pro (ID3 around these parts) colorimeter, last year they went on sale often for about $150 (normally $225-250). Learning HCFR (mentioned in Augerhandle's post) and how to interpret the graphs has a bit of a learning curve but once everything "clicks" it's not too bad. The problem with the Mits sets is like I said the color isn't linear. In other displays like LCD when you calibrate to the 75% or 100% Saturation color patterns the 50%, 25%, and 0% generally correctly fall in line. In a nutshell with the Mits if for example you calibrate to the 100% Saturation patterns then 75% is wrong, 50% is close to correct, 25% is wrong, etc. The built in CMS (color management system) can't correct this, only an external 3DLUT can. The blue on the Mits are wrong too and if you get a meter the CMS controls for it barely change it and 3DLUT's can't entirely correct for it either but much better than the built in CMS.
If you don't want to buy a meter download the AVS HD 709 disc or mp4's (This is also useful if you have a meter as it has patterns for it too):
Read the manual first. But basically set your brightness and contrast to the black and white clipping patterns (just be careful not to set contrast too high to avoid eye fatigue). There's a pattern for sharpness. Then do the Flashing Color Bars pattern, gotta put the TV in blue only mode (in the advanced user defined mode) then set color and tint. It's not accurate but it's much better than the built in modes.

That's not calibration since there's no objective data for interpretation.

I calibrate about every 3 to 4 months with a few touch ups of the Contrast due to lamp aging. My family uses the TV a lot so I have to swap lamps about once a year.
Regarding non Mits lamps. My last lamp is from one of the discount lamp web sites (discounttvlamps, it was half the price of a genuine Mits lamp) and while this isn't exactly scientific in recording this anomaly but I noticed that without my 3DLUT color correction 100% Red saturation pattern the red appears red-orange and I can't even get it remotely close to what 100% Red is supposed to be with the built in CMS, only with 3DLUT correction have I been able to get it back to pure red. I do not recall my genuine Mits lamps doing this. Maybe my DLP is getting old and something is wrong with it, maybe it's the lamp, I don't know but next lamp will be genuine Mits.
