I occasionally used proxies from this list:
http://tools.rosinstrument.com/cgi-b...r=1&filter=ALL
(You may have to hit "Submit" on that page--it needs to set a cookie before it allows you to see the list) but I got tired of the unreliability, slowness and security risks of using someone else's proxy. I ended up setting up my own proxy server using
CGIProxy.
All you need to do to use CGIProxy is find a web hosting service that provides cgi-bin access (unfortunately, not free... but I use my web host for many other services that make it well worth the few dollars per month) and then plop the CGIProxy script on the server.
I've been happily retrieving bone-headedly blocked sites quickly and reliably ever since. (And sorry, I will not reveal its address. I've learned the hard way that it's best to keep your personal proxies to yourself.)
