A number of TNPCers responded to a recent article with their own recommendations for auto-FTP programs.
TNPCer Ian B. likes GetRight from Headlight Software. With
GetRight you can schedule downloads and when a download is
complete have it disconnect or even shut down your system.

From Down Under, Ian W. highly recommends Bullet Proof FTP that
lets you specify files to download, their download order, handles
reconnection and picks up where it left off, and will even log
off and reconnect if you are on a metered site and exceed your
download time credit. You can have it monitor the clipboard and
when you copy an FTP or HTTP URL and filename to the clipboard it
will automatically start downloading the file in the background.
