Foxtrot tango, papa?

Does anyone know of / can recommend a good free / cheap FTP client that'll do reasonably clever and option-laden synching of directory content? Something like WinSCP, only for FTP?

Edit: Being more specific, features I'd like to see include:

* with a small number of clicks, it compares a remote directory (and recurses down into subdirectories) with the previously-specified local equivalent, presents me a list of which files are newer at which end, and will then (again with a small number of clicks) upload or download as appropriate to sych the ones I want to be synched;

* options to include hidden files in the comparison, exclude certain types of files by extension, ...

* remember directory presentation options;

* refresh local directory automatically when changes made in other apps (this seems a simple feature, but I've yet to find it);

* can keep conections to more than one server open at once;

* can configure keep-alive options;

* can synch (as above) remote servers with each other (via invisible local temp copy, presumably);

* easy to chmod, chown, chgrp;

* keps informative log of operations;

* make coffee.

But at least they didn't boil him alive

Guy reports having Craig Murray's book confiscated off him at Luton Airport. Bet he wishes he'd waited for the paperback now.

My favourite line: “Does it have al-Qaida in it?”

Maybe it should come with a cover warning along the lines of "Caution: this product may contain traces of al-Qaida. Do not take when attempting to get on board heavy machinery."
