Get a great picture for next to nothing.
Back in the days when a decent TV cost $4,000, I never hesitated to recommend spending $300 or so on professional calibration. But now you can get a pretty good set for less than $1,000. Far be it from me to tell you what your priorities should be, but to me, spending three bills to have a $900 TV calibrated seems as silly installing a $10,000 Viking range a 30,000 mobile home.
