What's a good SSH tunneling client for OS X?

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?
