www.safeweb.com is really good.
There is also a good software called JAP/JONDO that is free and easy to learn to use.
How it works
Instead of connecting directly to a webserver, users take a detour, connecting with encryption through several intermediaries, so-called
Mixes. JAP uses a predetermined sequence for the mixes. Such a sequence of linked mixes is called a
Mix Cascade. Users can choose between different mix cascades.

Other ways to hide your ISP:
VPN
VPN stands for Virtual Private Network, and is an increasingly popular form of proxy for security and to stay anonymous on net. VPN is a tunnel over the Internet. Each VPN connection is totally anonymous on the internet and it helps to keep your activities anonymous and safe. VPN internet access is an attractive option for people worried about their security and privacy.
SSH
SSH, the
Secure Shell, is a standard protocol that encrypts communications between your computer and a server. The computer being connected to must be running an ssh
daemon, or server, process. The computer which is attempting to connect must be running an SSH client. The encryption prevents these communications from being viewed or modified by network operators.
IPV6
IP, the Internet Protocol, is one of the pillars which supports the Internet. Almost 20 years old, first specified in a remarkably concise 45 pages in RFC 791, IP is the network-layer protocol for the Internet.
In 1991, the IETF decided that the current version of IP, called IPv4, had outlived its design. The new version of IP, called either IPng (Next Generation) or IPv6 (version 6), was the result of a long and tumultuous process which came to a head in 1994, when the IETF gave a clear direction for IPv6. IPv6 is designed to solve the problems of IPv4. It does so by creating a new version of the protocol which serves the function of IPv4, but without the same limitations of IPv4. IPv6 is not totally different from IPv4: what you have learned in IPv4 will be valuable when you deploy IPv6. The differences between IPv6 and IPv4 are in five major areas: addressing and routing, security, network address translation, administrative workload, and support for mobile devices. IPv6 also includes an important feature: a set of possible migration and transition plans from IPv4.
