Bare-bones UI, but it works well
Its a very bare bones FTP Client (even for anonymous connection you have to enter anonymous as a user name and a bogus password) that essentially just implements basic up/download functionality, but for the price of a dollar it works well. Id love to see the FTP Messages as well (The OS X Debug Console shows some limited information but not the full FTP exchange) but as a simple up/download tool its working fine.
