I just found out a few weeks ago that my ISP, Sonic.net, offers an IPsec VPN endpoint to all of its customers, with no additional fees. I highly recommend them if you're in the SF Bay Area.

Note that while their help page suggests that you use the Cisco client software to connect to their VPN endpoint, the service works just fine with Mac OS X's built-in Cisco IPsec client, as well as with the IPsec client in iOS. Dunno about other platforms, but Sonic.net provides the Cisco client for Windows and GNU/Linux, at least.
