Think before you speak pcdoc, read:
American release dates and prices:
PX-712A - late April - $209
PX-712SA - May - $229
Currently the official MSRP for the DVR-107 is $229 I believe, so it's really not any more, and this will be faster, higher quality, and SATA.
Of course, shops like newegg and the like will carry it for even less...
