I need a camcorder to begin shooting professionally.

I do not plan to make a long description of my problem. I need to choose between these three camcorders:

-Sony HDR-FX1 -HD, prosumer.
-Sony DSR-PD170 -XLR, professional.

Please, if you know which one I should get, say so in a DESCRIPTIVE way; say why and why not to choose the camcorders.

Thank you, I appreciate it.
