Low Cost VPN Solutions?

whschwartz asks: "I'm looking for a low cost solution for allowing myself and a few others the ability to share a server at one of our locations. One thought was using SSH tunnels to establish secure connections, forwarding any ports needed by our apps. We'd want to be able to map network drives, control the server with something like PC Anywhere or VNC with the possibility of running apps that have remote data on the server. I use the Cisco VPN solution for work, but that's not in our price range and is probably overkill. Are there any other options I should be looking at other than using SSH port forwarding?"
