In my never ending search of not spending money on certain things I ran into a great FTP client that handles secure connections. More and more FTP servers are requiring that you use some sort of secure connection and not all clients will handle that but WinSCP does a great job. It's free and it's for windows so if that meets your criteria you're good to go. I use it in Windows 7 and Server 2008 without any hiccups.
