Van Dyke, who make CRT and SecureCRT, also make SecureFX. It is a a pretty good program that does FTP, SSH over FTP and SFTP. The latest version supports SFTP transfers both in ASCII and Binary mode, which is really nice.
SFTP is great, because all you need running is SSH2. You don't even need an FTP Daemon installed on the server.
I'm pretty sure you can download a 30 Day Trial from the Van Dyke Website.
