Well...they're certainly proud of that little guy aren't they! $459 to get SFTP and $900 if you want to authenticate using Active Directory on a Windows server...ouch!
Still...if it meets your needs, what's price have to do with i right? But that still shuts out anything but pro/business users. Hmm...that's one way to cut out endless calls from people trying to use things they really can't be bothered to learn something about. So maybe that's also part of their pricing strategy. I worked once with a company that did exactly that - price their admittedly complex products to exclude casual users and tire-kickers. This was done purely to cut down on support requests.
Side note: Wing also publishes a very nice SFTP client that they'll let you download and use for free. It's called FTP Rush
and you can find out more about it here

Try the Free FTP client now and never look back!
I use the portable version on my 'fieldbox' USB key, and it works beautifully whenever I need to grab or transfer files. It also supports FXP server-to-server
transfers! (If you know what FXP is, you already know why you absolutely want this feature if you're working with servers that support it.)
So, if you've been a long-time Filezilla user, take a few minutes to download and try Rush instead.
They're right BTW. You probably won't go back to using FZ once you do.
