What is a good proxy service to use?

Hi Reddit,

I work in IT and tend to have a bit of downtime. I really like Reddit, but imgur is blocked at work and so are some sub-reddits (like r/gaming and r/pics). So I paid for a proxify account so I could log in to Reddit for my frontpage and look at pictures.

The problem is through proxify, and maybe something with my restricted browser settings at work, I can't interact with anything on the comment page. I can't upvote, comment, or even expand threads. So I would usually just wait until I found something awesome, and if it was on an unblocked sub-reddit I would log straight in normally and upvote and comment or whatever. Until recently when they changed the setting and broke Reddit completely.

Does anybody know of another proxy service that plays nice with Reddit?
