Turns out tor was unsuccessful for whatever reasons... Just got Firefox mad. So after a lot of Google-age, I came across Charon, made by a guy called Rhino. It finds IPs for you, tells you where they're from and if they're anonymous. All you have to do is tell your browser to run through that IP as a proxy and hey presto, you're logging in from china (even got Google errors in Chinese).
Thanks for getting me headed down the right path...
And if anyone's interested in Charon... click here
I found the search for IPs went on forever, and never displayed them. It's easier to join an IP archive forum (who knew they'd be out there?) and load lists from them and have Charon check through for anonymous ones, and compare the speed and ping of all the IPs... Exciting stuff.
