I've been using SSH Tunnel manager to easily set up and stop port tunneling over SSH to various servers at my company. That saved me the pain of opening up a new terminal window which will hang out there just for the sake of having a tunnel open.
This worked great (well , sort of) but SSH Tunnel Manager is a PowerPC application. With Lion, it is not supported any more.
What is a good replacement?
Use RDC (Remote Desktop Connection Client for Mac 2)
This free download runs natively on both Intel-based and PowerPC-based Macs
Use One Mac, unlimited Windows.
Being the fanboy that I am, I completely admit that I am absolutely in love with Prompt (by Panic). It's already come a long way since it's initial release, and here's a few wonderful features;
It's not cluttered. They provided an app that offers what you need out of an SSH client and added a few bonuses that make it so much more worthwhile.
Command, and parameter, auto-completion. (Oh my god this is amazing.)
Public/Private key authentication support. Well documented, and also quite improved in recent versions with regard to how to load the actual key.
Leveraging the amount of free space in the meta key bar, you can assign 4 "favorite special character keys", so pick the ones you use most often so you rarely have to hit the 123 keyboard key, or worse, the #+= key. I currently have /\.- chosen.
Prompt is $8 (universal app!) on the iTunes App Store.

SSHTunnel is a free, cocoa-based UI for SSH tunnel management. Works on 10.5 and up. It hasn't been updated in a while but the code that's there is reasonably stable. It's worked well for me in the past.
