I'm not trying to push a site but I just picked up a pile of proxy sites/domains and the one I find the fastest and simplest of the pile is
http://www.cgi-proxy.info
.. Loads super fast for me. I have another one on the same server/ip but it loads slow, feel free to check it out

As for proxy sites and owning them, they suck alot of bandwidth and reap little return on adsense. They are usefull for some people though and can be considered a contribution to slacking off at work
Anyhow.. my pile of proxies, about 10 or so are up and running and fully functional but not re-designed yet and not fully looked over other than making sure the TOS of google arent being broken by myself. As far as I see they run off phproxy and such. I still have to read their terms.
If you bother to check them out, let me know if you see anything that needs to be dealt with.
