You seem to be very confused. It is true that some devices may convert from one standard to another, but, as a semi-pro in video, please believe me when I say camcorders can record only in one format. So it is with the camera you cite. From Sony's website:
Convert and/or record any analog NTSC video source to digital video via the analog inputs. Analog NTSC video can also be passed through the digital Handycam Camcorder directly into a PC via the i.LINK® interface in real-time for easy PC editing of your analog footage.
If you want a PAL version, you need the DCR-HC90E and you won't find that in the States.
Personally, I would not buy a Sony consumer camcorder (their Pro models are stupendous). They are over-priced for their quality and give us (us being the beta testers for a large video software maker) far more hassle than all the other makes combined. I would favour, above all, a Panasonic in this price range, which is hassle-free.
You could shop around within the EU, so that you would not be charged either duties, luxury tax or VAT. Some countries may have cheaper prices than others. On the whole, the UK has reasonable prices and so has Germany (make sure you get the English manual, though), but bargains may be found elsewhere.
