A lot of the time good proxies are hard to find. Sometimes they are unreliable, slow or plain just don't work.
Here is a good one I have come across. You can access from school or work and is not listed with major filtering technologies. HERE
It has a development project on the TLD so many spiders will not see any reference to a proxy. It's free, easy to use, and has only a small ad on the front page. It's fast and even resumes small downloads.
You can use it to access games like evony, as well as sites like facebook, gmail, hotmail, stuffpoint and so much more!
It will even allow you to use SSL and encrypt your browsing session. Hide browsing history, get around filtering at work or school, or just surf anonymously.
