I recently wanted the same thing, but went for the ultra cheap route of buying a Thecus YES Nano hard-drive enclosure.
It supports USB on-the-go, so you can plug a USB card reader into it, press the copy button on the Nano and it copies everything to the internal hard disk.
It cost me about £15 (around $30), but you obviously have to supply your own hard disk.
It's has a separate battery back (4 * AA's), and copies a GB in a few minutes (the colorspace copies 1GB/minute I think) - but it works and cost a fraction of the price.
A word of warning - if you do go this route, it's a little picky about the HD's you can put in it so do some research on the net and find a combination that works. I've only got 20GB in it at the moment, but there's been plenty of success with 100GB drives.
Alternatively, you can buy a HD enclosure (generic) for less than £5, and a Asus EEEEEEEE PC thing for less than £200. Plug CF card and HD into the EEEEE PC and copy between the two. This is still cheaper than a Colorspace enclosure, although a bit bigger.
Just a few thoughts.
Oh, incidentally, a recently UK camera magazine (Digital Camera) just did a review of storage devices included Canon/Epson pricey ones, Colorspace, Jobo Giga and Digitmate III. They liked the Digimate best - around £80 for 80GB.
