If I (and this is just me) had say $1300 to spend I would not spend 1000 on a TV and then get it calibrated. I would spend the entire amount on the TV.
Now if I was spending maybe 2-3k on a TV I may consider procalibration.
Others may have different priorities but I would much rather get a 55 inch ST (as an example) than a 50 inch and get it calibrated. Size matters.
