Is it worth to have my TV professionaly calibrated

[Stephan.klose]

I have the Samsung LE37 A 552. (For about 3 weeks now).

I heard from a friend that you can have your TV professionally calibrated.

I watch mostly Blu Ray and HD-DVD.

I also heard it's pretty expensive.

My question: Does is pay off? I mean is it worth it?

Does anyone had it done to their system?

Is it even sensible to have $2000 (yeah, that's what it cost in Austria) TV calibrated or should I just go with the factory settings. Although I know a lot about all the technical aspects and such of TV's I really am not that well versed in matters of calibration. In the store, where I work I would doubt that anyone else would know more than any of you guys. That's why I am asking. (If you have Hi-Fi Questions, I am your man)
