My favorite is WS_FTP Pro... Another very nice one is WebDrive -- it installs a shell extension that allows you to map a windows driveletter to any FTP site, and transparently does the FTP stuff...
Through WebDrive you can save a file directly to your site from within any program, move files around through the windows explorer or even from the command line.
