I used to use AlFTP too when it was first released. Nice app but at the time I had a few problems (they are probably fixed now).
Before that I used the paid verision of Ipswitch WinFTP which is very good but I got fed up with the expensive updates (AKA bug fixes).
Now I used Directory Opus to save having another tool handy.
Actually I like the idea of WinSCP if it has puTTY incorporated - I might give it a looksee.
