My vote would be for Free Download Manager. I've used Fresh
Download and Star in the past, but I have been delighted with
FDM, especially in concert with Firefox's FlashGot extension.
You can read about it here:

It does require installation onto a hard drive first, so it's
not *exactly* what you were asking for, but I transferred it to
my memory key and I've been using it for a while with no
problems. Perhaps it will meet your needs anyway.
