If you need a nice file manager and file transfer client, I recommend ForkLift. I got it from Bundlehunt. At the time of writing this post the bundle expired but check Bundlehunt from time to time to see if ForkLift is in the bundle.
I use it for SSH connections with my server to upload blog posts from my computer. One of the best feature is the one or two-way sync.
I decided to use a file transfer client because I can't run the Dropbox client on my server anymore. ForkLift does its job perfectly since my requirements are not high. If you want to try a more popular file transfer client, there is Transmit.
Time to publish this post with ForkLift :).
