And at the low end of the market, has anyone tried this:

http://www.acard.com/english/fb01-product.jsp?idno_no=382&prod_no=ANS-9010BA&type1_idno=5&ino=28

The Acard ANS-9010BA seems cheap and, if not plentifully available,
at least available on ebay and amazon.

It's battery backed and will auto backup to a CF card, which seems
pretty cool for something that is cheaper than the big boys' toys.

Sometimes cheap is good.  Sometimes cheap is a disaster. :-)  Has anyone
discovered which camp this one is in, when used as a ZFS ZIL?

Cheers,

Stephen.
