I very very very highly recommend using the ftp command from command line. If you really insist on something else, ncftp is also a very nice command line ftp program.
Or, if you really want to use something with a GUI, use the Finder (seehttp://www.lowendmac.com/x-basics/03/0211.html for a quick tutorial on using the Finder this way). After all, why use a 3rd party program when you have them already built in.
