My #2 recommendation is Hide My Ass.
Although this tends to be slightly more expensive than some other options, it's still an affordable way to keep you secure online.
Many people like Hide My Ass because it's relatively easy to use and set up, and it's very large. Being large means that there are many IP addresses to choose from, which gives you more access to certain content.
Along with security in numbers, being closer to a specific server will also help with speed. So if you want to access blocked content from a specific location, it's nice to be on a server close to that location.
One of the negative things you might hear about Hide My Ass is the whole issue of data logging. If you're not sharing copyrighted files, then you really have nothing to worry about. But if you're torrenting illegal information, you might want to consider some other options.
Bottom line, most people will not have any issues with the small amount of data that is temporarily logged by Hide My Ass. For this reason, along with the benefits above, it's still a great choice.
